New Feature in Cisco IOS Release 12.2(8)MC2b Software
The following new feature is introduced in Cisco IOS Release 12.2(8)MC2b.
Traffic Recovery Over MLP After T1 Failure
When a T1 failure occurs, traffic recovers over the MLP link within 6 seconds.
This caveat is a feature enhancement to the keepalive interface configuration command. With this
enhancement, you can also configure a maximum number of retries before a link is declared down by
issuing the command as follows:
enhancement, you can also configure a maximum number of retries before a link is declared down by
issuing the command as follows:
keepalive [interval] [retries]
where:
•
interval is the keepalive interval (in seconds). Valid value is a number greater than 0. The default
is 10.
is 10.
•
retries is the number of times a link will be tried again before being declared down. Valid value is a
number between 1 and 255. The default is 5.
number between 1 and 255. The default is 5.
For implementation in an IP RAN solution, the recommended configuration is as follows:
On the MWR 1900:
interface Serial0/0:0
no ip address
encapsulation ppp
keepalive 1 2
no cdp enable
ppp multilink
multilink-group 1
end
On the MGX-RPM-1FE-CP back card;
interface Virtual-Template2
bandwidth 1536
no ip address
keepalive 1 2
no peer default ip address
ppp multilink
multilink-group 101
end.
Note
In the MGX-RPM-1FE-CP backcard configuration example, only the keepalive interface command and
configuration recommendation is specific to implementation in an IP RAN solution.
