Performance Routing Pfr / OER Woes........

Hello again Guy's

Im trying to get PFR working and having a few issues in lab enviroment, I am currently just looking to get a basic PFR fast failover to, upon which i can build further policies/labs. But alas i am having little luck......

PS The master is also a BR:

Firstly the 2 BGP Routes at the MC:

*>                           200 4445 4445 i

* i                   0    100      0 i

With a secondary static for good measure:

#show run | i ip route

ip route

ip route 255 name TestSecondaryRoutePFR

#show pfr master

Performance Routing Pfr / OER Woes........


You have defined a learn-list called "Learn_List_Remote1_Prefix" in your learning section.

But in your pfr-map you reference the access-list instead of the learn-list. If you plan to use the automatic learning, then you have to use the learn-list name in your pfr map, ie:

pfr-map Remote_1_General 100

match pfr learn list Learn_List_Remote1_Prefix
