configured, set by the string of
up to 31 characters.
in– incoming routes filtering;

the update along with other routes
(optional, none for vpnv4).
esr(config-bgp-neighbor-af)#
default-originate
37 Set the mode in which all updates are
sent to BGP neighbor with the IP
address of a local router outgoing
interface as the next-hop (optional,
none for vpnv4).
esr(config-bgp-neighbor-af)#
next-hop-self
38 Define the precedence of the routes

<VALUE> – neighbor routes
precedence, takes values in the

esr(config-bgp-neighbor-af)#
remove-private-as [ { all | nearest |
