We have problem con EIGRP and two ASR 1001 in High Availability. ASR2 have received all route (100 route) from PE, but in ASR1 doesnt received all route (75 route) from PE or from other ASR02. All PE have all route. The ASR1 when modify or lost some route dont update to the ASA. see diagram.
EIGRP routers also have their Router ID, similar to OSPF. If two routers happen to have the same EIGRP Router ID, they may mutually ignore networks they advertise themselves. You should check for an EIGRP Router ID conflict.
On both ASRs and on PE, issue the show ip eigrp topology command and check for the heading of this output. For example:
R1#show ip eigrp topo
IP-EIGRP Topology Table for AS(1)/ID(22.214.171.124)
Notice the highlighted ID - that is the EIGRP Router ID. Make sure that this Router ID is distinct and unique on all three routers.
Should this be okay, it will probably be necessary to see your configuration on ASR1.
However, at this point, I am not yet willing to admit this is an IOS bug. Let's continue debugging the issue. When you issue the show ip eigrp topology on the ASR1, do you see the missing routes at least in the topology table? How many networks should you have in your routing table, anyway?
I think ASR1 router should receive all routes from PE so you can verify this with sh ip eigrp top all command. This command will tell you if there is any route failing feasible condition because different PE routers in SP network.
Also, I don't know if EIGRP peering is needed between ASR routers if these routers should receive same routes from PE. ASA should create ECMP load balancing to both ASR routers.
