Configuration Guide
Note:
The dialer threshold command takes effect only on dial MP links. It does not take
effect on non-dial MP links and dial links with MP disabled.
You need to configure the dialer threshold command only at the calling end.
If the dialer threshold 0 command is configured, DCC may bring up all available
links and the dialer timer idle command becomes invalid.
II. Implementing MP by setting the lower limit of links in an MP bundle
Some dial applications may require multiple links to carry service. To this end, you may
configure the ppp mp min-bind command, allowing the router to bring up multiple
when triggered to ensure minimum bandwidth. The following is how MP operates in this
case:
1) The router brings up the first link.
2) When the first link comes up, the router checks whether the number of links in the
MP bundle reaches the lower limit specified by the min-bind-num argument. If not,
the router brings up the second link.
This process continues until the number of links in the MP bundle reaches the lower
limit.
Perform the following configuration in dialer interface view.
Table 1-15 Configure MP by setting lower limit of links in an MP bundle
Enable MP
Configure the lower limit of links in an
MP bundle
By default, no lower limit of links is set for MP bundling.
Note:
Configure PPP commands on both dialer and physical interfaces to ensure reliable
PPP link negotiation.
Similar to the dialer threshold 0 command, the ppp mp min-bind command voids
the dialer timer idle command. When it is configured, the router does not look at
traffic size to bring up links for MP bundling or tear down links that have been
brought up.
