Complete Configuration Example; Triggering Ancp Oam - Juniper IP SERVICES - CONFIGURATION GUIDE V 11.1.X Configuration Manual

Complete Configuration Example

The following example contains the commands used to configure ANCP. You can
customize and use this example in your own network.
You can copy the text into a text editor and modify it (removing all prompts and
changing values) for immediate use or save the modified example as a script (.scr)
file. Script files allow you to execute commands as though they were entered at the
terminal. For information about creating and executing script files, see Command
Line Interface in JUNOSe System Basics Configuration Guide.

Triggering ANCP OAM

The l2c oam command provides an access-line test and rudimentary fault isolation
capability for the B-RAS. Issuing this command triggers the access node to perform
a loopback test on the local-loop (between the access-node and the CPE). The B-RAS
generates a GSMP port management message to the neighbor specifying the access
line identifier on the access node and OAM test characteristics desired by the B-RAS
(for example, the number of cells/message to generate and the timeout period). The
When Subscriber A requests to join 232.1.1.1, ANCP transmits an add branch
message with the corresponding input and output labels that cross-connect
port 3 and port 6 on Access Node 1.
!Configure an OIF map
host1(config)#ip igmp oif-map OIFMAP atm 2/0.101 232.1.1.1 10.1.1.1
host1(config)#ip igmp oif-map OIFMAP atm 2/0.102 232.1.1.2 10.1.1.2
!Define ANCP parameters
host1(config)#l2c
host1(config-l2c)#session-timeout 15
!Enable ANCP to listen to OIF mapping events from IGMP in this virtual router
