322 | | Let's start Configuring the connectivity between core network (!CampusCore, FacACore and FacBCore). |
| 320 | ==== Core Network Layer==== |
| 321 | |
| 322 | Let's start Configuring the connectivity between core network (!CampusCore, FacACore and FacBCore). We will start from CampusCore. |
| 323 | |
| 324 | - Login to CampusCore device. Give your console port password (class password) |
| 325 | - Go to config mode from user mode. Give your enable password (class password) |
| 326 | - Core network runs on VLAN 2. Create VLAN 2 and name it '''Core''' |
| 327 | {{{ |
| 328 | CampusCore(config)# vlan 2 |
| 329 | CampusCore(config-vlan)# name Core |
| 330 | CampusCore(config-vlan)# exit |
| 331 | }}} |
| 332 | - Then assign the IP Address to the VLAN interface. Get the IP from the [#point1 table] |
| 333 | {{{ |
| 334 | CampusCore(config)#interface vlan 2 |
| 335 | CampusCore(config-if)# ip address 10.0.2.1 255.255.255.0 |
| 336 | CampusCore(config-if)# exit |
| 337 | }}} |
| 338 | - Finally configure fast ethernet interfaces switchport modes. You can find then from the [#point2 table] |
| 339 | * Fisrt make the interface a trunk port. This is for the FacACore link |
| 340 | {{{ |
| 341 | CampusCore(config)#interface FastEthernet 1/0 |
| 342 | CampusCore(config-if)#switchport mode trunk |
| 343 | }}} |
| 344 | * Define the encapsulation |
| 345 | {{{ |
| 346 | CampusCore(config-if)#switchport trunk encapsulation dot1q |
| 347 | }}} |
| 348 | * Give the Description of the interface |
| 349 | {{{ |
| 350 | CampusCore(config-if)#description Core link to FacACore |
| 351 | CampusCore(config-if)#exit |
| 352 | }}} |
| 353 | * Follow the same procedure for FacBCore link |
| 354 | {{{ |
| 355 | CampusCore(config)#interface FastEthernet 1/1 |
| 356 | CampusCore(config-if)#switchport mode trunk |
| 357 | CampusCore(config-if)#switchport trunk encapsulation dot1q |
| 358 | CampusCore(config-if)#description Core link to FacACore |
| 359 | CampusCore(config-if)#exit |
| 360 | }}} |
| 361 | |
| 362 | - You have successfully configured the CampusCore device for you core networks connectivity. Let's move on to FacACore device. |
| 363 | {{{ |
| 364 | FacACore(config)# vlan 2 |
| 365 | FacACore(config-vlan)# name Core |
| 366 | FacACore(config-vlan)# exit |
| 367 | FacACore(config)#interface vlan 2 |
| 368 | FacACore(config-if)# ip address 10.0.2.2 255.255.255.0 |
| 369 | FacACore(config-if)# exit |
| 370 | FacACore(config)#interface FastEthernet 1/15 |
| 371 | FacACore(config-if)#switchport mode trunk |
| 372 | FacACore(config-if)#switchport trunk encapsulation dot1q |
| 373 | FacACore(config-if)#description Core link to CampusCore |
| 374 | FacACore(config-if)#exit |
| 375 | }}} |
| 376 | |
| 377 | - Now let's configure FacBCore |
| 378 | {{{ |
| 379 | FacBCore(config)# vlan 2 |
| 380 | FacBCore(config-vlan)# name Core |
| 381 | FacBCore(config-vlan)# exit |
| 382 | FacBCore(config)#interface vlan 2 |
| 383 | FacBCore(config-if)# ip address 10.0.2.3 255.255.255.0 |
| 384 | FacBCore(config-if)# exit |
| 385 | FacBCore(config)#interface FastEthernet 1/15 |
| 386 | FacBCore(config-if)#switchport mode trunk |
| 387 | FacBCore(config-if)#switchport trunk encapsulation dot1q |
| 388 | FacBCore(config-if)#description Core link to CampusCore |
| 389 | FacBCore(config-if)#exit |
| 390 | }}} |
| 391 | |
| 392 | - Finally Verify the connectivity |
| 393 | * Go to FacACore device |
| 394 | * Go to privileged mode and ping CampusCore and FacBCore |
| 395 | {{{ |
| 396 | ping 10.0.2.1 |
| 397 | ping 10.0.2.3 |
| 398 | }}} |
| 399 | * You should get a positive reply with '''"!!"''' |
| 400 | |
| 401 | ==== Distribution Network Layer ==== |
| 402 | |
| 403 | Let's Start Configuring the distribution layer of your campus LAN. Here you will have to configure both Layer 3 switches (FacACore and FacBCore) and Layer 2 Switches (FacASw and FacBSw). Let's start from Layer 3 devices. |
| 404 | |
| 405 | - Login to FacACore device |
| 406 | - Go to config mode from privileged mode |
| 407 | - FacACore is the Core device in Faculty A and It can have different departments. In this scenario department 1 is in faculty A and It's VLAN is VLAN10. Create VLAN 10 and Name it '''Dept1''' |
| 408 | {{{ |
| 409 | FacACore(config)# vlan 10 |
| 410 | FacACore(config-vlan)# name Dept1 |
| 411 | FacACore(config-vlan)# exit |
| 412 | }}} |
| 413 | - Then assign the IP Address to the VLAN interface. Get the IP from the [#point1 table] |
| 414 | {{{ |
| 415 | FacACore(config)#interface vlan 10 |
| 416 | FacACore(config-if)# ip address 10.0.10.254 255.255.255.0 |
| 417 | FacACore(config-if)# exit |
| 418 | }}} |
| 419 | - Next configure fast ethernet interfaces switchport modes. You can find then from the [#point2 table] |
| 420 | * Fisrt make the interface a trunk port. |
| 421 | {{{ |
| 422 | FacACore(config)#interface FastEthernet 1/0 |
| 423 | FacACore(config-if)#switchport mode trunk |
| 424 | }}} |
| 425 | * Define the encapsulation |
| 426 | {{{ |
| 427 | FacACore(config-if)#switchport trunk encapsulation dot1q |
| 428 | }}} |
| 429 | * Give the Description of the interface |
| 430 | {{{ |
| 431 | FacACore(config-if)#description link to FacASw |
| 432 | FacACore(config-if)#exit |
| 433 | }}} |
| 434 | - Follow the same procedure for FacBCore device. VLAN 20 name is dept 2. |
| 435 | {{{ |
| 436 | FacBCore(config)# vlan 20 |
| 437 | FacBCore(config-vlan)# name Dept2 |
| 438 | FacBCore(config-vlan)# exit |
| 439 | FacBCore(config)#interface vlan 20 |
| 440 | FacBCore(config-if)# ip address 10.0.20.254 255.255.255.0 |
| 441 | FacBCore(config-if)# exit |
| 442 | FacBCore(config)#interface FastEthernet 1/0 |
| 443 | FacBCore(config-if)#switchport mode trunk |
| 444 | FacBCore(config-if)#switchport trunk encapsulation dot1q |
| 445 | FacBCore(config-if)#description link to FacBSw |
| 446 | FacBCore(config-if)#exit |
| 447 | }}} |
| 448 | - Now the Core devices are done, Let's Configure Layer 2 devices. Login to FacASw |
| 449 | - Go to config mode |
| 450 | - Create Vlan 10 and Give a Name |
| 451 | {{{ |
| 452 | FacASw(config)# vlan 10 |
| 453 | FacASw(config-vlan)# name Dept1 |
| 454 | FacASw(config-vlan)# exit |
| 455 | }}} |
| 456 | - Next configure fast ethernet interface which connects to the Core device and give a description |
| 457 | {{{ |
| 458 | FacASw(config)#interface FastEthernet 1/15 |
| 459 | FacASw(config-if)#switchport mode trunk |
| 460 | FacASw(config-if)#switchport trunk encapsulation dot1q |
| 461 | FacASw(config-if)#description link to FacACore |
| 462 | FacASw(config-if)#exit |
| 463 | }}} |
| 464 | - Configure fast ethernet interface, which connects to the User PC to an access port of VLAN 10 and give a description |
| 465 | {{{ |
| 466 | FacASw(config-if)#switchport mode access |
| 467 | FacASw(config-if)#switchport access vlan 10 |
| 468 | FacASw(config-if)#description link to Dept1PC |
| 469 | FacASw(config-if)#exit |
| 470 | }}} |
| 471 | - Follow the same steps for FacBSw |
| 472 | {{{ |
| 473 | FacBSw(config)# vlan 20 |
| 474 | FacBSw(config-vlan)# name Dept2 |
| 475 | FacBSw(config-vlan)# exit |
| 476 | FacBSw(config)#interface FastEthernet 1/15 |
| 477 | FacBSw(config-if)#switchport mode trunk |
| 478 | FacBSw(config-if)#switchport trunk encapsulation dot1q |
| 479 | FacBSw(config-if)#description link to FacBCore |
| 480 | FacBSw(config-if)#exit |
| 481 | FacBSw(config-if)#switchport mode access |
| 482 | FacBSw(config-if)#switchport access vlan 20 |
| 483 | FacBSw(config-if)#description link to Dept2PC |
| 484 | FacBSw(config-if)#exit |
| 485 | }}} |
| 486 | - You have configured your distribution layer. Check and verify the connectivity |
| 487 | * Go to Dept1PC and try ping the gateway (VLAN 10 Interface IP of FacACore) |
| 488 | {{{ |
| 489 | ping 10.0.10.254 |
| 490 | }}} |
| 491 | * You should get a reply |
| 492 | * Try the same in Dept2PC |
