ASR Inter-chassis redundancy and PAT

[anazarenko]

I started playing with ASRs in the LAB and came to to interesting problem with more than 2 BGP Uplinks.

I noticed that the ASR blocks the asymmetric traffic if the incoming interface has a different redundancy RII number.

But at the same time I cant assign the same redundancy RII to 3 links to my carriers. Does anybody know if I can do multi-provider BGP redundancy with 3 ISPs and stateful NAT?

Does anybody using ASR Inter-chassis redundancy? How reliable is it?

I tried to upgrade one of the routers in a redundant pair and it was restarting for about 10 times before becoming stable.
