We need to configure BGP with 2 ISP on Single Router, with load balancing and failover. The current configuration is providing load balancing but if ISP1 link goes down, then browsing stops but if ISP2 goes down then we are able to browse. We have added 2 default routes for both ISP. The network diagram is attached.
Our BGP configuration is:
router bgp ZZZZZ
no synchronization
bgp log-neighbor-changes
network 3.3.3.0 mask 255.255.255.0
redistribute static
neighbor 1.2.3.1 remote-as XXXXX
neighbor 1.2.3.1 soft-reconfiguration inbound
neighbor 2.2.3.1 remote-as YYYYY
neighbor 2.2.3.1 soft-reconfiguration inbound
no auto-summary
ip route 0.0.0.0 0.0.0.0 1.2.3.1
ip route 0.0.0.0 0.0.0.0 2.2.3.1
