Example 3: Create an iBGP Connection with a Loopback
Interface
Loopback interface is often used as a BGP connection because it is always up on the
network, unlike a physical port, for which the link might be down. This example shows how to
set up an iBGP connection with loopback interface between Switches D and E. You create
static routes or use an IGP protocol such as OSPF or RIP to configure the switch to reach the
IP address of loopback interface.
Since NETGEAR BGP does not support multihop eBGP, eBGP cannot be established with
loopback interface.

Configure iBGP on Switch D

1. Create VLAN 200 with IP address 172.126.2.1.
