Dual uplinks with single 5400 and single 6509 (with multiple interface cards)

[miked]

I have a single 5400 with two gige ports and a single 6509 with dual gige line cards.

What would be the best method for running them with dual connections in case an interface or line card goes bad?

Thanks in advance.

Anyone?

Does anyone know a good alternative to "ip sla" on a 6509? I can't believe the 6509 doesn't support "ip sla".

So the 6509 supports rtr and track but the "ip route" statement doesn't support the "track" attribute??? Man, I just can't catch break!!!

Nobody??? Anybody???

Hi miked,

I have 6509s in my environment and I run IP SLA ( ICMP probes) with static routes and they support the track feature. What IOS level are you at?

The AS5400 supports routing, no? Can you configure you 6509 to use routed ports facing the 5400, then you can configure routing (EIGRP/OSPF) between the 5400 and 6509? Or are you limited to using static routes between the devices?

Thank you for the reply Joseph. I swear I've ran SLA on 6500's before. This box is running IOS 12.2 so maybe that's the culprit.

I found a simple way to configure both devices redundantly using administrative distanced routes pointing through a specified interface. On the 6509, the routes point to a loopback address on the 5400, on the 5400 it's configured as default routes. Like this document explains:

Seems to work like a champ.
