In this Free CCNP Lab you will use GNS3 to configure two routers to use static routes to load balance BGP over dual-path connections between the two routers. By default BGP chooses only one path to a remote network. To enable any type of load balancing of two or more connected paths you can use static routes to the remote peer address.
In BGP, if the next hop address in EBGP is not used, and you want to configure load balancing you need to enable EBGP multihop to establish the EBGP peer. Also due to the fact that the next hop address is not a directly connected address BGP needs to advertise the updates source IP address to EBGP.
Learning Objectives:
- Learn to configure ebgp-multihop.
- Learn to configure update-source.
- Learn to advertise update source IP addresss.
- Learn to prevent loops in BGP.
- Learn to use static routes to achieve load-balancing of two or more paths.
