frame relay ,multipoint sub int , inverse arp, dlci

[sarahr202]

Hi every body

1)Let say we have head quarter-router connected two sides, over two vc, dlc1,dlc2.  Let assume  we are using one subnet and multipoint  sub int on head quarter-router

Head quarter config;

int s0/0

encapsulation frame-relay

int s 0/0.1 multipoint

ip address 199.199.199.1/24

My question is  do i have to configure dlci on head quarter-router or lmi protocol will inform head quarter-router which dlci are active?

what about inverse arp? will it map  the ip addresses to dlci on this interface( multipoint sub int)

=================================================================================================

Let say we have two sides, connected by frame relay over vc

side1----------------------------------------------side 2

Let say both sides are using point to point sub interface

side1 uses dlc1 to reach side 2

side 2 uses dlc2 to reach side 2

My question is do  i have to associate dlci with interface  using  commands or lmi  can do that for us ?

thanks  and have a nice day.

Is your head-quarter router acting as a FrameRelay -Switch between Side 1&2 ?? How are the connections?

thanks for your reply.  heade quarter -router is connected to frame relay  network.

Hi

For point-to-point you must put the frame-relay interface-dlci command because inverse-arp is disabled.

For point-to-multipoint you can let inverse-arp do the job  using frame-relay interface-dlci command  or you can use static maps using frame-relay map command

Regards.

Thanks .

Can we enable enable inverse arp on point to point sub int?

what about dlc on multiport sub int?  we must configure dlci on such int or lmi can take care of it ?

thanks.

This should give you more clarity

1. Point to Point Subinterface
2. Hub and Spoke Subinterfaces
