When you configure MC-MLPPP on a port, consider the following guidelines:
MC-MLPPP can be enabled on every MLPPP bundle
MC-MLPPP must be enabled before links are added
links inside an MC-MLPPP bundle must be configured for access mode and IPCP encapsulation type. All links must be from the same adapter card and all timeslots must be allocated to a single channel group.
a single fragment size for all classes is supported
prefix elision is not supported, as per RFC 2686. The prefix elision (compressing common header bytes) option advises the router that, in each of the given classes, the implementation expects to receive only packets with a certain prefix; this prefix is not to be sent as part of the information in the fragments of this class.
Use the following CLI syntax to configure MC-MLPPP.
config port {bundle-id}
multilink-bundle
mlppp
multiclass count
The following CLI syntax shows an example of configuring MC-MLPPP.
config# port bundle-ppp-1/6.1
config>port# multilink-bundle
config>port>multilink-bundle# mlppp
config>port>multilink-bundle>mlppp# multiclass 4
config>port>multilink-bundle>mlppp# exit
config>port>multilink-bundle# exit
config>port# exit
config#
Use the config port info command to display port configuration information.
NOK-B>config>port# info
