HA config in route-domains?
I am creating different traffic groups for different route domains so that a failure in traffic-group one does not effect the other and only the effected traffic-group failsover.
I am running ver 11.2 hf1 on 1600 platforms.
Have few questions -
1. For each route domain i am defining a seperate external, internal and a HA vlan. The HA vlan is completely private tagged on directly connected links b/w the two 1600s. Should i define a separate HA-vlan for each route domain and then add them to the "failover unicast configuration" one-by-one as I go? It curently just has the mgmt interface and the HA interface of the default route domain.
2. Should I use mac-masqurade address in each traffic-group? I might have a total of 20+ traffic groups/route domains so should i go that far in defining each one with a seperate mac address or just leave it default?
3. Under the "mirroring configuration" I only have the primary local mirror address and the secondary local mirror address of the HA and the Internal interface of the default route domain. I might never do a connection mirroring as majority of the traffic will be HTTP, but just in case I have to do it in the future for a VIP residing in a seperate route-domain, then how will the connections be mirrored b/w the 2 devices for a differnt route-domain as I do not have an option to add another addresses in there?
thnx

- Akhtar_109015NimbostratusHi Sandev, did you found answers to your queries ? if yes please share your experience, since I am into the same situation ? Regards, Akhtar
- sandy16AltostratusNo, it was getting far complicated so I left the route domains config. We just designed it without the route domains.

You should keep your HA config in RD0 rather than provide one for each route domain. Just setup the other details in separate RDs.
Do you have VRRP/HSRP configured in neighbouring routers? If so then you should use MAC masquerading and use a separate MAC address for each traffic group. If you don't use VRRP/HSRP then I can see no reason to use MAC masquerading other than local policy reasons.
Note that a sync-failover cluster can only support 15 traffic groups. I'm working hard with my SE to get this changed as we were using them but bumped our head on the 15 maximum.
