I would be a bit concerned about the 2951 processing 2 copies of the full Internet routing table. We do not know anything about your environment, but I suspect that if we found out more it is likely that there is not much benefit to you from receiving full Internet routes from either provider. I would suggest that it might be a good design for you to ask the provider on the 100 connection to send only the default route and to use local preference to prefer this route. And to ask the provider on the 50 connection to send you default and partial routes and use local preference so that at least this default route will function as backup to the route on the 100 connection. The partial routes received will direct some traffic over the 50 connection and the default route on the 100 connection will get the rest of the traffic. And you have failover if either of the providers experiences a problem.
If you did download full tables for each router then how would you want to load balance the traffic because presumably you would want to favour the 100Mbps line ? If you did then with all those routes how are you going to decide which routes go down one link and which go down the other. That's an awful lot of configuration for not much gain.
If the bandwidth was the same on both links then perhaps it would be worthwhile.
I think RIck's suggestion is a good one. Of course it depends on how much traffic is sent to the partial updates eg. if the partial updates included facebook, google etc. then you may find the 50Mbps link is overutilised but there are no guarantees with this sort of thing.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
