Whilst configuring VRFs on Sup1A-2GE cards, I have run into a small issue with HSRP.
Once the relevant VLAN is placed into the VRF instance, icmp can reach both real IPs but not the HSRP standby ip.
A check of the VRF arp table shows no entry for the virtual IP but it can be found in the standard ARP table.
I have attempted to configure the arp vrf entries but I get"Bad ARP command - Interface may only be specified when bridging IP" when using the Vlan statement at the end, as follows:
arp vrf ABC 1.1.1.1 0000.0c07.acdf ARPA Vlan 123
IOS allows me to enter arp vrf ABC 1.1.1.1 0000.0c07.acdf ARPA but this doesn't allow icmp to the virtual IP.
I am not having the same issue on the Sup720s we use and wonder if it is a limitation in the 12.1.8b(E14) IOS or perhaps the fact that ISLs are used instead of 802.1q between these switches.
Any help/advice is greatly appreciated.
