Configure to permit the
routes with their AS
numbers contained in
their AS_PATH attributes

(this operation can also
specify the number of the
AS number occurrences
allowed)

allow-as-loop
[
number
]
Optional
By default, routes with
their AS numbers
contained in their
AS_PATH attributes
being the local AS number
are denied.
Note:
AS number contained in the AS_PATH attribute can be used for route loop detect. With
EBGP running between a MCE and a site, the routes advertised by an MCE device to
the site carry the local AS number. So do the routes advertised by the site. In this case,
you need to configure to permit the routes with their AS numbers contained in their
AS_PATH attributes being the local AS number on MCE devices for the routes
advertised by the site to be received and processed by the MCE device.

Configuration on the site
Note:
The site configuration procedures vary with device model. The following takes an
S3610&S5510 Ethernet switch as an example. As for switches from other vendors,
refer to the corresponding user manuals.
