BGP Failover

[Stephen Carville]

I am trying to get bgp failover working between two routers.  BGP is up with both ISPs but I cannot figure out how to get the failover working.  I've been reading various documentation fro two days now and I am still stuck.  My ASN is 393235.  The ISPs are 3549 and 20115.

          +--------[WAN-1] <=> [ASN 3549]
          |
[internal network]
          |  
          +--------[WAN-2] <=> [ASN 20115]

Here is what I have so far:

-------------------------------------------------
WAN-1

interface Port-channel1
 description LAN
 ip address 74.202.136.1 255.255.255.0 secondary
 ip address 198.204.115.2 255.255.255.0
 standby 1 ip 198.204.115.1
 standby 1 priority 200
 standby 1 preempt
 no negotiation auto
end

router bgp 393235
 bgp log-neighbor-changes
 network 198.204.112.0
 network 198.204.115.0
 neighbor 209.234.172.13 remote-as 3549

track 1 ip sla 1 reachability
 delay down 35 up 35
!
track 2 ip sla 2 reachability
 delay down 35 up 35
!
track 3 ip sla 3 reachability
 delay down 35 up 35
!
track 10 list boolean or
 object 1
 object 2
 object 3

Hello Stephen,

the link below has numerous failover/load balancing sample setups. Specifically look at Topology 6 and 7 (since yous seem to have 2 PEs):
