MLPPP vrf aware

Hi all,

I've 2 7204VXR with 10 ISDN PRI.

I have different dialer belonging to different vrf: each dialer is associated to different PRI with rotary-group.

Can I configure the multichassis MLPPP within this scenario?

Obviously the 'sgbp member' will be done using the Loopback ip address that are in global routing table.

Thanks in advance

Re: MLPPP vrf aware

Multilink PPP (MLP) provides the capability of splitting and recombining packets to a single end system across a logical pipe (also called a bundle) formed by multiple links. MLP provides bandwidth on demand and reduces transmission latency across WAN links.

Multichassis Multilink PPP (MMP) provides the additional capability for links to terminate at multiple routers with different remote addresses. MMP can handle both analog and digital traffic.

This functionality is intended for when there are large pools of dial-in users and a single access server cannot provide enough dial-in ports. MMP allows you to provide a single dial-up number to the users and to apply the same solution to analog and digital calls.

MMP support on a group of routers requires that each router be configured to support MLP, Stack Group Bidding Protocol (SGBP) and Virtual Profiles, as shown:

SGBP: A stack group is a collection of two or more Cisco routers, or access servers, that are configured to operate as a group and support MLP bundles with links on different systems. SGBP identifies the bundle location of a stack member within a defined stack group. SGBP also arbitrates for a designated stack member for the bundle creation.

Virtual Profiles, the virtual template used for cloning interface configuration to support MMP, is a unique PPP application. It creates and configures a virtual access interface dynamically when a dial-in call is received and tears down the interface dynamically when the call ends. Virtual Profiles work with straight forward PPP and with MLP.
