トップページ/動作検証 ネットワーク系/20100325 スイッチをDynamipsで設定 - DynagenでCCIEを目指す

目的

• Dynamipsでスイッチの基本的な設定方法を確認します。

構成

• 設定概要
  • SWを介して3台のルータを接続します。
• 構成図

• netファイル

検証1 疎通確認

• ping応答の確認

R1#ping 192.168.1.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/46/52 ms
R1#ping 192.168.1.3

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.3, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 16/41/68 ms

• ARPの確認

R1#show arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  192.168.1.1             -   cc00.0e14.0000  ARPA   FastEthernet0/0
Internet  192.168.1.3             0   cc02.0e14.0000  ARPA   FastEthernet0/0
Internet  192.168.1.2             5   cc01.0e14.0000  ARPA   FastEthernet0/0

• CDPによる確認

CDPの表示を見ると、Dynamipsで定義したスイッチは表示されないようです。

R1#show cdp neighbor
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
                  S - Switch, H - Host, I - IGMP, r - Repeater
