Syntax loop-detect {drop-peer | discard-route | ignore-loop| off}
no loop-detect
Context config>service>vprn>bgp
config>service>vprn>bgp>group
config>service>vprn>bgp>group>neighbor
Description This command configures how the BGP peer session handles loop detection in the AS path.
This configuration parameter can be set at three levels: global level (applies to all peers), group level
(applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most
specific value is used.
Note that dynamic configuration changes of loop-detect are not recognized.
The no form of the command used at the global level reverts to default, which is loop-detect ignore-
loop.
The no form of the command used at the group level reverts to the value defined at the global level.
The no form of the command used at the neighbor level reverts to the value defined at the group level.
Default loop-detect ignore-loop
Parameters drop-peer — Sends a notification to the remote peer and drops the session.
discard-route — Discards routes received with loops in the AS path.
ignore-loop — Ignores routes with loops in the AS path but maintains peering.
off — Disables loop detection.
med-out
