Eigrp - How to modify Admin distance for redistributing connected links and over WAN

59 Views
Last Modified: 2016-12-14
We have a single EIGRP domain 101 across 2 locations (A and B) separated by a WAN link. Each location has a number of L3 switches at the IDF behind the router which has  the L3 vlans VL1, VL2 etc. We run eigrp 101 across all the switches and on the routers but we dont advertise any of the L3 vlans on them and we do redistribute static and connected for the static and the vlans to be distributed on eigrp.

Qn

1. How do i reduce the admin distance of the directly connected vlan on IDF on our core switch. ie. Vl1 and Vl2 that are distributed via connected has a admin distance of 170 locally as the other switches sees that as External without having to advertise the networks individually on each switch.  

2. Is that possible to increase the admin distance over the WAN link without having to create a 2nd eigrp domain. ie.. Add a admin distance of say 50 over the WAN link  and that way devices on both sides do see that there is a 130 distance for the remote side and 90 for local for admin distance.

Why?
I am trying to separate two locations and i don't think we will be able to create an additional domain and i am trying to see alternate methods of achieving this.
