Chris,

Here is a working GLBP config. I have changed the IP addresses to private
nets for security reasons.
!
These routers are on the same LAN, 2 different ISPs to the Internet, both
routers running BGP.
!
ROUTER A
interface FastEthernet0/0
  description Link to xxx
  ip address 192.168.63.1 255.255.255.0
  speed 10
  half-duplex
  glbp 10 ip 192.168.63.254
  glbp 10 priority 254
  glbp 10 preempt delay minimum 7
  glbp 10 weighting 100 lower 95
  glbp 10 authentication text xxx10
  glbp 10 weighting track 2 decrement 20
  glbp 10 forwarder preempt delay minimum 7
