Frame Relay interface configuration

My question is about interface and sub-interface configuration for frame relay. In my studies and simulations I have learned that one can use point to point subinterfaces, a physical interface configured with inverse arp, or static mapping with the frame-relay map command. Can multiple frame-relay map commands be used on one interface to configure paths to multiple dlcis?

Re: Frame Relay interface configuration

Hi,

multiple map commands can be configure on fram relay multipoint interfaces.In case of point to point no mapping is required.

A ?multipoint? interface by definition is an interface that may connect to multiple end points of a network. Both physical interfaces and multipoint subinterfaces in Frame-Relay are by definition ?multipoint?.

see this for fr introduction: http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/frame.htm

hope this will help

rgrds,

Hi,

Yes you can have multiple FR map statements on a multipoint interface. For some good examples regarding frame relay configuration have a look at the Cisco IOS Wide-Area Networking Configuration Guide, Release 12.4, Chapter "Configuring Frame Relay" at

This should pretty much answer all your questions.

Hope this helps! Please use the rating system.
