defining default gateway

[axfalk]

We have a couple of Layer 3 switches (Cat-6506) that are etherchannelled together. There are 8 Vlans defined on the switches and we need to configure HSRP on the vlan interfaces. When the HSRP is configured on a vlan int, what would be the default gateway for the hosts on that vlan, the address of the HSRP group or the address of the vlan virtual interface?

Thanks.

Address of the HSRP group. (Typically defined using "standby 1 ip ".

Thanks for your response. When I do a traceroute from a host on a vlan that has HSRP configured, the next hop points to that vlan's virtual interface, not the HSRP group????

Thanks again.

This is as it should be and is not a problem.

When you do the traceroute, the response packet is generated by the router/switch and it uses the IP address assigned to the inteface as the source not the HSRP shared address. This is by design. If the response packet had the HSRP address it would then become potentially ambiguous which machine had generated the response.
