[carl_townshend]

Can anyone tell me how to configure frame relay between 2 sites, using inverse arp, and without inverse arp .

thanks

carl,

you can find whatever you want in frame relay configuration:

remeber to rate the post if it helps

Hello,

in addition to the other posts, here is a configuration example for a frame relay connection with and without inverse-arp:

No inverse-arp configs:

Router1

interface Serial0

ip address 192.168.1.1 255.255.255.252

encapsulation frame-relay

frame-relay map op 192.168.1.1 102

frame-relay map ip 192.168.1.2 102 broadcast

no frame-relay inverse-arp

Router2

interface Serial0

ip address 192.168.1.2 255.255.255.252

encapsulation frame-relay

frame-relay map ip 192.168.1.2 201

frame-relay map ip 192.168.1.1 201 broadcast

no frame-relay inverse-arp

Inverse-arp configs:

Router1

interface Serial0

ip address 192.168.1.1 255.255.255.252

encapsulation frame-relay

Router2

interface Serial0

ip address 192.168.1.2 255.255.255.252

encapsulation frame-relay

Obviously, this configuration requires an actual frame relay connection. If you have a DTE/DCE cable and two routers with serial interfaces, you can also fairly easily build a back-to-back frame relay connection. Here are a couple of links to the respective setups:

thanks for that, so which connection do we need to do frame relay maps on, would i have to do them on both point to point and multipoint ?

[carl_townshend]

how come on the first config, you have mapped its own ip on the interface as well as the remote router ?, also do you always need to reverse the dlci on the other end ? i thought the dlci can be anything, do they have to be reversed ?
