To verify that each pair of CE routers has end-to-end connectivity, issue the ping command on routers CE1, CE2, and CE3:
CE1 to CE5 (red VPN)
user@CE1> ping 10.11.4.100
PING 10.11.4.100 (10.11.4.100): 56 data bytes 64 bytes from 10.11.4.100: icmp_seq=0 ttl=252 time=1.216 ms 64 bytes from 10.11.4.100: icmp_seq=1 ttl=252 time=1.052 ms ^C --- 10.11.4.100 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max/stddev = 1.052/1.134/1.216/0.082 ms
CE2 to CE6 (blue VPN)
user@CE2> ping 10.21.4.100
PING 10.21.4.100 (10.21.4.100): 56 data bytes 64 bytes from 10.21.4.100: icmp_seq=0 ttl=252 time=1.205 ms 64 bytes from 10.21.4.100: icmp_seq=1 ttl=252 time=1.021 ms ^C --- 10.21.4.100 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max/stddev = 1.021/1.113/1.205/0.092 ms
CE3 to CE7 (VPLS)
user@CE3> ping 10.1.1.2
