directly connected or HSRP - on 6500

[prakadeesh]

Hello,

I have two 6500 say c1 and c2, intrerconnected via trunk. Now they both have HSRP and PVST running on them. The PVST is inline with the HSRP active state. Say for even vlans c2 is HSRP active and root, for odd valsn c1 is hsrp active and root. Now one of the machines with say IP address 10.4.4.4 ( vlan 4 , even vlan)is connected to c1. Now if a packet to 10.4.4.4 arrives on c1 may be from a different VLAN or say a WAN , will c1 use the IP ARP table in it and forward it using the directly connected link OR will is see c2 as the HSRP active for this even vlan and fwd to C2 to take the l3-l2 decision, now c2 will anyways fwd the packet back to c1 as the 10.4.4.4 is conencted to c1. Please help me get round this issue.

thanks,

Hello Prakadeesh,

traffic from host 10.4.4.4 will use the c1-c2 link to reach VIP address.

return traffic may come back via c1 or via c2.

if via c2 the c1-c2 is used also on return path else c1 will resolve 10.4.4.4 and forwards the frame to host directly

Hope to help
