Sup 720 Redundancy

[netops01]

Hi

6506, 2 x Sup 720. IOS 12.2 (WAN services). What is the best way to ensure redundancy if a Sup fails? I do NOT want HSRP (dont ask!). Will RPR/RPR+ work with MSFC3/PFC3?

Any hints people...

yes it support RPR/RPR+

look at this:http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_guide_chapter09186a00802e4a9c.html

remeber to rate this post if it helps

You should really look at SSO/NSF. This has significantly better fail-over times that RPR/RPR+.

This can provide 50ms fail-over times, if the routing protocol you are using and the neighbors support NSF.

Thanks, but I use OSPF and ALL the other routers are not NSF aware. No budget to change that either.....
