BGP
The basic BGP configuration consists of adding a neighbor entry for each peer and configuring an export
filter. BGP can operate in two modes: External BGP (EBGP) and Internal (IBGP). EBGP is used between
BGP routers that are in different Autonomous (AS) systems and IBGP is used between BGP routers in the
same ASes (to redistribute routes learned from external BGP routers to internal BGP routers). The mode
is not configured explicitly but is activated based on AS number configuration for the local BGP router
and the neighbor. When the AS number is different, BGP operates in EBGP mode and when it is the same
it operates in IBGP mode. In the example below, BGP is configured with one external neighbor with
LOCAL_LAN as the export filter.
Navigate to Routing-> Basic Config->BGP
Select ‘LOCAL_LAN’ as the export filter.
