next-hop-self
Syntax [no] next-hop-self
Context config>service>vprn>bgp>group
config>service>vprn>bgp>group>neighbor
Description This command configures the group or neighbor to always set the NEXTHOP path attribute to its own
physical interface when advertising to a peer.
This is primarily used to avoid third-party route advertisements when connected to a multi-access
network.
The no form of the command used at the group level allows third-party route advertisements in a
multi-access network.
The no form of the command used at the neighbor level reverts to the value defined at the group level.
Default no next-hop-self — Third-party route advertisements are allowed.
peer-as
Syntax peer-as as-number
Context config>service>vprn>bgp>group
config>service>vprn>bgp>group>neighbor
Description This command configures the autonomous system number for the remote peer. The peer AS number
must be configured for each configured peer.
For EBGP peers, the peer AS number configured must be different from the autonomous system
number configured for this router under the global level since the peer will be in a different
autonomous system than this router
For IBGP peers, the peer AS number must be the same as the autonomous system number of this
router configured under the global level.
This is a required command for each configured peer. This may be configured under the group level
for all neighbors in a particular group.
Default No AS numbers are defined.
Parameters as-number — The autonomous system number, expressed as a decimal integer.
Values 1 — 65535
