hi group,

if i have a frame-relay back to back connection between two routers and
i turn off LMI by using "no keepalive", what is the difference between
using "frame-relay interface-dlci..." and "frame-relay local-dlci"?

i have tried both methods, and both works just fine...

thanks

configuration:

R2(config-if)#do sh run int s0/1

interface Serial0/1
 ip address 172.16.25.2 255.255.255.224

 frame-relay map ipv6 FEC0::25:5 205
 no frame-relay inverse-arp
