I'm prepping our ASR9001-S for integration as BNG, we have a M-LAG based core for aggregation and routing... so basicallyy we have...
The idea was to connect each BNG 1x10G to each of the agg's for subscribers (eg. BNG1->AGG1&AGG2) and then 1x10G to each of the cores for ospf/routing (eg. BNG1 ->COR1&COR2), and use GeoRed for HA, so we'd have layer 2 redundancy, and GeoRed redundancy to protect against switch and router failures.
But then i remembered, our 9001S only has 2 active 10G ports according to the specifications, so we're sort of stuck either we connect the ports together on a bundle and have wan and lan on same bundle, or have the units only connected to 1 node of the agg and cor switches, which I suppose would work, and give clean 10/10 Gigabit ... but no l1 redundancy per unit, only the geo-redundancy for ha.
Just wondering what you guys think, I don't foresee getting the 2x120 license financed to activate the other 2 internal ports, and the MPA's are currently out a budget to add more ports, so we're basically stuck with what came with the boxes.
Whats odd is I notice theirs no actual mention in the config or interfaces of tengige0/0/2/2 and 0/0/2/3 being disabled by the current license or is that just something that I won't see till I plug those ports in.
