Hi all:
I'm seing this sample config in the doc CD about using bri subinterfaces
with frame relay encapsulation:
interface BRI0
no ip address
encapsulation frame-relay
dialer string 4155551212
dialer-group 1
frame-relay lmi-type q933a
!
interface BRI0.1 multipoint
ip address 10.1.100.1 255.255.255.0
frame-relay interface-dlci 100
frame-relay interface-dlci 110
frame-relay interface-dlci 120
!
interface BRI0.2 point-to-point
ip address 10.1.200.1 255.255.255.0
frame-relay interface-dlci 200 broadcast IETF
!
access-list 101 deny igrp any host 255.255.255.255
access-list 101 permit ip any any
dialer-list 1 protocol ip list 101
I've never used a config like this with ISDN , and i'm wondering:
1-This config is a bit curious for me. You have two subinterfaces in the
router, each one on a different subnet and however you only have 1 dial
string applied to the fisical interface. Anyone can suggest where this
config maybe usefull and why? (in the CD only is displayed the config of 1
router, not the entire scenario)
2-The dlci you define in one end of the isdn network must be the same at
the other end to properly work?
Thank you very much for your help and best regards
