Routing (more)
ISP border routers at the IXP should not be configured to carry the IXP LAN network within the IGP or iBGP
- Set BGP next-hop to local router (Cisco IOS next-hop-self)
Don’t generate ISP prefix aggregates on IXP peering router
- If connection from backbone to IXP router goes down, normal BGP failover will then be successful
