Trying to find what it the best method of doing intervlan routing with a 2691 router connected to a 3750 with 2900's as distribution switches.
The documentation that I have read on cisco's site says to use a default route from the 3750 to the 2691 router and then on the router have routes for each subnet. Is there any issue to running a routing protocol (in this case EIGRP) here?
No there is absolutely no issue. It really depends on
1) how many vlans you are creating
2) If there are any other L3 devices (other than your 2691) that you need to exchange routing information with.
A few vlans and static routing/default route works wells but it can soon become a pain once your number of vlans grows.
