esr(config-bgp-neighbor)#
address-family { ipv4 | ipv6 |
vpnv4 } unicast

ipv 6 – IPv6 family;
vpnv4 –VPNv4 family.
35 If prefix list filtering mode is selected,
add subnet filtering in incoming or
outgoing updates ( Mandatory when

esr(config-bgp-neighbor-af)#
prefix-list <PREFIX-LIST-NAME>
{ in | out }
<PREFIX-LIST-NAME> – name

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

38 Define the precedence of the routes
