○cisco simulatorの続き

以下の構成で、仮想ルータを起動する。



dynagenの.netファイルを以下に設定して起動する。

ルータが起動したら、telnetしていつもどおり設定
R1のconfigを抜粋

とりあえずIPつけただけです。

PE-R1#show ip interface brief

各intがupしていること
で、対向int-ipまでpingが通るところまで確認

PE-R1#ping 192.168.13.3 repeat 10
Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 192.168.13.3, timeout is 2 seconds:
!!!!!!!!!!
Success rate is 100 percent (10/10), round-trip min/avg/max = 4/8/16 ms
PE-R1#ping 192.168.14.4 repeat 10
Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 192.168.14.4, timeout is 2 seconds:
!!!!!!!!!!
Success rate is 100 percent (10/10), round-trip min/avg/max = 4/75/668 ms
PE-R1#

次回R1-R4でMLPSネットワークを構成する。ここからが本番

(2012/09/7追記)
MPLS網で、CE-PE-P-PE-CEのpathを明示的に構成するため、R1 F0/0 <--> R3 F0/0のlinkをshutdownしました。
