Does wccp redirect break routing protocol?

[TCAM]

This may be a dumb question to ask, sorry i don't have equipment to test it at this moment.

If wccp redirect is configured on an interface running routing protocol (such as eigrp or ospf), will this redirect the "unicast" ospf database or eigrp topology update to WAAS?  and/or will this also redirect ospf & eigrp "multicast" update which maintains neighbor relationship to WAAS?

Should this type of traffic be denied on wccp redirect-list?

Thanks

Hi Joe,

Since WAAS normally uses TCP promiscuous mode services, based on service group number 61 and 62 - you'll only get TCP redirected ... and neither OSPF nor EIGRP runs on top of TCP, so don't worry.

If you run a TCP based routing protocol like BGP, it will get redirected.

Later versions of WAAS don't, by default, try to optimize on BGP, as it has given some problems in the past due to sequence number manipulation.

Thanks Finn -

oh, that right, I forgot about "unicast" database and topology updates are still running over ospf/eigrp protocol 89 & 88 respectively, so it will not be intercepted by wccp process.  I do aware of the bgp is tcp based.

Thanks
