Looking for a little help. Trying to implement PfR on a 2851 as a means to perform multi-homing in a non-BGP environment with two static links. I have put together the following and hoping for some feedback before live implementation! Any help GREATLY appreciated! Here is the sample config (IP addresses have been changed to protect the innocent!) Sample config: Current configuration : 6641 bytes version 12.4 service timestamps debug datetime msec localtime service timestamps log datetime msec localtime service password-encryption ! hostname SAMPLE ! ip cef ! no ip domain lookup ip domain name sampledomain.com ip name-server x.x.x.x ! multilink bundle-name both ! controller T1 0/2/0 framing esf linecode b8zs channel-group 0 timeslots 1-24 description Qwest Bonded T1-1 ! controller T1 0/2/1 framing esf linecode b8zs channel-group 0 timeslots 1-24 description Qwest Bonded T1-2 ! !
