EBGP Load Balancing Example: Scenario #1
Loopback interfaces are used to configure load balancing for EBGP between two ASes over two parallel links.
This example consists of the following:
Enabling BGP function
Configuring loopback addresses
Adding static routes
Configuring peers
Configuring inbound and route redistribution policies
In the following diagram:
Nokia Platform A is in autonomous system AS100, and Nokia Platform B is in autonomous system AS200.
Nokia Platform A has a loopback address of 1.2.3.4, and Nokia Platform B has a loopback address of 5.6.7.8.
