[c-nsp] Cisco ASR920-24SZ-IM BVI Feature Limitations

[Darin Herteen]

Greetings,


I'm in the processes of evaluating a ASR920-24SZ-IM for a variety of services and I'm struggling to find a definitive list of feature limitations as they pertain to BVI interfaces and time constraints aren't going to allow me to lab all permutations.


I've reviewed the slide deck from Waris's ASR900 & ASR920 Product Family Technical Webinar as well as some other decks I have and as informative as they are they are only listing scale.


I've done a quick run using:


http://www.cisco.com/c/en/us/support/routers/asr-920-24sz-im-router/model.html#ConfigurationGuides


And it doesn't appear that any guide on the page touches on BVI/IRB, however I continue to search.


Even though I know they are not the same, I'm currently basing what features and I can, and cannot offer on a BVI based on a Trident Chipset using a A9K-16T/8-B/A9K-40GE-B as it is the lowest scale LC I deal with where I would otherwise terminate a customer service on a BVI. (http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r5-1/interfaces/configuration/guide/hc51xasr9kbook/hc51irb.html)


Anybody know off the top of their head whether this assumption is too restrictive and/or inappropriate?


Thanks in advance,


Darin
