folks


i have 2 sites linked on the external interfaces by a 10Mb circuit


in each site i have a hsrp cluster which is working fine BUT when i enable the link between site A & site B i get problems and hsrp drops, comes up, drops etc


i've tied the issue down to an acl but i have a query


i want the cluster on site A to be the main cluster so i'm planning to use the standby priority and set them to


site A 120 & 115

site B 110 & 105


is this a feasible solution to ensuring that site A, while it is up, remains as the primary site


sorry if this is a bit vague but its a lot more complex involving BGP on the outside and no site to site link on the internal interfaces ( i may have to use different hsrp group for this?)


thanks to anyone taking the time to read this or who makes the effort to respond


greatly appreciated


ps - any good hsrp design guides links would also be appreciated

For connectivity you can use any dynamic routing protocol, not just BGP. Don't know if other are option as well. HSRP is basically a LAN technology.


HSRP on both sides if on the same media should use separate group numbers.


Thanks.

If all your 4 routers require to present a single redundant next-hop, one HSRP group is fine. HSRP requires the media to be a broadcast domain.


Thanks.
