Match Aggregated Route
The Match Aggregated Route feature helps to match BGP aggregated route from the non-aggregated route. BGP can aggregate a
group of routes into a single prefix before sending updates to a neighbor. With Match Aggregated Route feature, route policy separates
this aggregated route from other routes.

Remove Private AS in Inbound Policy
BGP appends its own as-path before sending out packets to neighbors. When a packet traverses multiple iBGP neighbors, the as-path
structure will have many private autonomous systems (AS) in them. The Remove Private AS in Inbound Policy will give the capability
to delete those private autonomous systems using RPL route-policy. The remove as-path private-as command removes autonomous
systems (AS) with AS number 64512 through 65535.

Set Administrative Distance
The Set Administrative Distance modifies the administrative distance of each of the individual prefixes in BGP. When RIB has two
routes to the same destination, RIB chooses the route with lower administrative distance for forwarding. The
set-administrative-distance command sets the administrative distance of BGP route to a value such that RIB chooses the route which
is required.

EIGRP Support for BFD
EIGRP supports Bidirectional forwarding detection (BFD) for link failure detection.
