This brief article explains how create a simple F/R Configuration.
Physical Topology:
Logical Topology:
============================================================ Hostname : R1 Platform : 2621XM IOS : 12.3 ============================================================ ! hostname R1 ! interface Serial0/1 ip address 10.1.1.1 255.255.255.0 encapsulation frame-relay no dce-terminal-timing-enable frame-relay map ip 10.1.1.2 102 broadcast frame-relay map ip 10.1.1.3 103 broadcast ! ============================================================ Hostname : R2 Platform : 2621XM IOS : 12.3 ============================================================ ! hostname R2 ! interface Serial0/1 ip address 10.1.1.2 255.255.255.0 encapsulation frame-relay no dce-terminal-timing-enable frame-relay map ip 10.1.1.1 201 broadcast frame-relay map ip 10.1.1.3 203 broadcast ! ============================================================ Hostname : R3 Platform : 2621XM IOS : 12.3 ============================================================ !
[EDIT] hostname R3 ! interface Serial0/1 ip address 10.1.1.3 255.255.255.0 encapsulation frame-relay no dce-terminal-timing-enable frame-relay map ip 10.1.1.1 301 broadcast frame-relay map ip 10.1.1.2 302 broadcast ! ============================================================ Hostname : FRSW Platform : 2621XM IOS : 12.3 ============================================================ ! hostname FRSW ! frame-relay switching ! interface Serial0/1 no ip address encapsulation frame-relay clockrate 64000 no dce-terminal-timing-enable frame-relay intf-type dce frame-relay route 102 interface Serial0/2 201 frame-relay route 103 interface Serial0/3 301 ! interface Serial0/2 no ip address encapsulation frame-relay clockrate 64000 no dce-terminal-timing-enable frame-relay intf-type dce frame-relay route 201 interface Serial0/1 102 frame-relay route 203 interface Serial0/3 302 ! interface Serial0/3 no ip address encapsulation frame-relay clockrate 64000 no dce-terminal-timing-enable frame-relay intf-type dce frame-relay route 301 interface Serial0/1 103 frame-relay route 302 interface Serial0/2 203 !
Verification:
thanx for the help, it cleared some concepts of FR and easily configure FR Switch
you’re welcome
fantastic it cleared all the doubts in multipoint configuration
No need for manual frame-relay map, inverse arp is automatically enabled for IPv4 over FrameRelay. (sh frame map | i dynamic or Dynamic)
R3 right conf
interface Serial0/1
ip address 10.1.1.3 255.255.255.0
encapsulation frame-relay
no dce-terminal-timing-enable
frame-relay map ip 10.1.1.1 301 broadcast
frame-relay map ip 10.1.1.2 302 broadcast
right, error of cut / paste, thx
I savor, cause I discovered just what I used to be looking for. You’ve ended my 4 day long hunt! God Bless you man. Have a nice day. Bye
Wonderful paintings! This is the kind of information that are supposed to be shared across the web. Disgrace on the search engines for no longer positioning this post upper! Come on over and consult with my web site . Thank you =)
