I have two CSS11503 in ASR Master/Backup configuration. The configuration worked correctly for two years, but one week ago the Backup CSS become the Master without any configuration changes. So now and two CSS work as Master and I have not service! I reboot the Backup one and after reboot it?s become master again. I think that the VRRP problems are occurs. I saw that the Backup CSS didn?t receive VRRP information:
CSS2(debug)# ip scp statistics
Packets received with supported protocol types:
IPPROTO_IP: 0 IPPROTO_ICMP: 804
IPPROTO_IGMP: 8 IPPROTO_GGP: 0
IPPROTO_TCP: 1829 IPPROTO_EGP: 0
IPPROTO_PUP: 0 IPPROTO_UDP: 179
IPPROTO_IDP: 0 IPPROTO_TP: 0
IPPROTO_EON: 0 IPPROTO_OSPF: 1451
IPPROTO_ENCAP: 0 IPPROTO_VRRP: 0
How can I troubleshooting the problem and could I check if the Master CSS send VRRP packets? I have not rebooted the master CSS yet!
