1
R1, R2, R3 segment is 17.1.1.0
1.
R4 do first rip
#rip 1
#version 2
#undo sum..
#netwokr 14.0.0.0
Do rip and ospf injection on R4
#ospf 1
#import rip type 1
#rip 1
#import-route ospf
2.
Frame Relay Configuration
In doing R1: (R2 and R3 with R1)
#int s3 / 0/0
#link-protocol fr
#fr map ip 17.1.1.1 102
#fr map ip 17.1.1.3 103 (ip ip as do the corresponding end of the src)
R2:
R3:
Done FR R1, R2, R3 interworking
R1 and R4 interworking
R3 R4 required mutual through means
In doing R1 (R2, R3 supra)
#ospf 1
#peer 17.1.1.1（r2ip）
#peer 17.1.1.3（r3ip）
At this time, R3 and R4 interworking
3.
The second experiment
Provided R1 is DB, R2 and R3 piecemeal need priority
R2 and R3 are the same
#int s3 / 0/0
#ospf dr-protocol 0
4.
R3, R5, R6 do rip
R3 and R5 do the virtual link
R3:
#ospf1
#area 2
# Vlink-peer 5.5.5.5 (peer router-id)
R：
#ospf1
#area 2
#vlink-peer 3.3.3.3
At this point the whole Netcom
