Disabling and Reenabling Loop Detection
By default, BGP resets a peer-to-peer session if it discovers a loop in the AS path.
You can use the BCC or Site Manager to disable and reenable loop detection.
Using the BCC
To disable or reenable loop detection, go to a BGP peer prompt (for example,
box;
ip; /jointfilesconvert/97454/bgp; peer/2.2.2.2/2.2.2.3
) and enter:
detect-as-loop
<
state>
state
is either
enabled
(default) or
disabled
.
For example, the following command disables loop detection on peer-to-peer
session 2.2.2.2/2.2.2.4:
peer/2.2.2.2/2.2.2.4#
detect-as-loop disabled
peer/2.2.2.2/2.2.2.4#
Using Site Manager
