EIGRP (in NBMA) Lab Preparation: Configure multipoint

Configure multipoint links. HQ is the hub, west and east are the spokes.

Router(config)#hostname HQ
HQ(config)#

HQ(config)#int se0/0

HQ(config-if)#no shut

HQ(config-if)#encapsulation frame-relay ietf
HQ(config-if)#exit

HQ(config)#int se0/0.1 multipoint
HQ(config-subif)#

HQ(config-subif)#ip address 172.30.10.1 255.255.255.248

HQ(config-subif)#frame-relay map ip 172.30.10.3 103 broadcast ietf

HQ(config-subif)#frame-relay map ip 172.30.10.2 102 broadcast ietf

Router(config)#hostname East
East(config)#

East(config-if)#encapsulation frame-relay ietf

East(config-if)#no shut
East(config-if)#exit

East(config)#int se0/0.1 multipoint
East(config-subif)#frame-relay map ip 172.30.10.1 201 broadcast ietf

Router(config)#hostname West
West(config)#

West(config)#int se0/0
West(config-if)#encapsulation frame-relay ietf

West(config-if)#no shut
West(config-if)#exit

West(config-subif)#frame-relay map ip 172.30.10.1 301 broadcast ietf

Before I start I should verify my configuration.

HQ#sh frame-relay map
Serial0/0.1 (up): ip 172.30.10.2 dlci 102(0x66,0x1860), static,
broadcast,
IETF, status defined, active
Serial0/0.1 (up): ip 172.30.10.3 dlci 103(0x67,0x1870), static,
broadcast,
IETF, status defined, active

West#sh frame-relay map
Serial0/0.1 (up): ip 172.30.10.1 dlci 301(0x12D,0x48D0), static,
broadcast,
IETF, status defined, active

East#sh frame-relay map
Serial0/0.1 (up): ip 172.30.10.1 dlci 201(0xC9,0x3090), static,
broadcast,
IETF, status defined, active

HQ#ping 172.30.10.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.30.10.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/8/8 ms

HQ#ping 172.30.10.3

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.30.10.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/8/8 ms
HQ#

So I am good to good 😉
