Router 3

View the firewall filter counter to continue verifying that matched traffic is being diverted to the bidirectional IPSec tunnel. After you issue the ping command from Router 1 (four packets), the es-traffic firewall filter counter looks like this:

Filter: es-traffic
Counters:
Name                                                Bytes              Packets
ipsec-tunnel                                          336                    4

After you issue the ping command from both Router 1 (four packets) and Router 4 (six packets), the es-traffic firewall filter counter looks like this:

Filter: es-traffic
Counters:
Name                                                Bytes              Packets
ipsec-tunnel                                          840                   10

To verify the success of the IKE security association on the ES PIC, issue the show ike security-associations detail command. Notice that the IKE SA on Router 3 contains the same settings you specified on Router 2.
