Yeah this is the way I d absolutely do it ! Marko sorry to bother you but what is the point of using Ip unnumbered loo0 on a P2P FR interface ? Does this can introduce some routing problems further with the IGP ? (I m not speaking about RIP and validate update-source here) but rather about Routing in General.
Thanks for the help :) Nic 2011/6/20 Marko Milivojevic <[email protected]> > What you described is the way to do it: > > R2: > > interface Loopback0 > ip address 192.168.0.2 255.255.255.255 > ! > interface Loopback1 > ip address 2.2.2.2 255.255.255.255 > ! > interface Serial0/1/0 > no ip address > encapsulation frame-relay > no frame-relay inverse-arp > ! > interface Serial0/1/0.205 point-to-point > frame-relay interface-dlci 205 ppp Virtual-Template1 > ! > interface Virtual-Template1 > ip unnumbered Loopback1 > ip ospf 1 area 0 > ! > router ospf 1 > log-adjacency-changes > network 192.168.0.0 0.0.0.255 area 0 > ! > > > R5: > interface Loopback0 > ip address 192.168.0.5 255.255.255.255 > ! > interface Loopback1 > ip address 5.5.5.5 255.255.255.255 > ! > interface Serial0/1/0 > no ip address > encapsulation frame-relay > no frame-relay inverse-arp > ! > interface Serial0/1/0.502 point-to-point > frame-relay interface-dlci 502 ppp Virtual-Template1 > ! > interface Virtual-Template1 > ip unnumbered Loopback1 > ip ospf 1 area 0 > ! > router ospf 1 > log-adjacency-changes > network 192.168.0.0 0.0.0.255 area 0 > ! > > Verification: > R2#sh ip ospf interface brief > Interface PID Area IP Address/Mask Cost State Nbrs F/C > Lo0 1 0 192.168.0.2/32 1 LOOP 0/0 > Vi1 1 0 Unnumbered Lo1 1 P2P 1/1 > Vt1 1 0 Unnumbered Lo1 1 DOWN 0/0 > > R2#show ip ospf neighbor > > Neighbor ID Pri State Dead Time Address Interface > 192.168.0.5 0 FULL/ - 00:00:31 5.5.5.5 > Virtual-Access1 > > R2#sh ip route ospf > 192.168.0.0/32 is subnetted, 2 subnets > O 192.168.0.5 [110/2] via 5.5.5.5, 00:02:15, Virtual-Access1 > > R2#ping 192.168.0.5 source Loopback0 > > Type escape sequence to abort. > Sending 5, 100-byte ICMP Echos to 192.168.0.5, timeout is 2 seconds: > Packet sent with a source address of 192.168.0.2 > !!!!! > Success rate is 100 percent (5/5), round-trip min/avg/max = 20/20/20 ms > > > -- > Marko Milivojevic - CCIE #18427 > Senior Technical Instructor - IPexpert > > FREE CCIE training: http://bit.ly/vLecture > > Mailto: [email protected] > Telephone: +1.810.326.1444 > Web: http://www.ipexpert.com/ > > > > On Sun, Jun 19, 2011 at 15:40, Daniel Gheorghe > <[email protected]> wrote: > > Hi, > > > > Is there any way of enabling OSPF on the interface level in a PPPoFR > > scenario using ip unnumbered on the virtual-templates? > > > > Let's say we have R1 - R2 connected via a FR cloud.
