OSPFv3_multipoint_adjacencies.cap (11.5 KB)

Packets: 73 Avg Size: 146 bytes Duration: 35.1 sec
Data Rate: 2.36 Kbps Added: 31 Aug 2008 Downloads: 357

The frame relay link connecting routers 1, 2, and 3 has been configured as a point-to-multipoint network with broadcast capability. Router 3 forms OSPFv3 adjacencies with routers 1 and 2, but no DR or BDR is elected.

OSPFv3_NBMA_adjacencies.cap (12.9 KB)

Packets: 86 Avg Size: 137 bytes Duration: 90.0 sec

Router 3 forms OSPFv3 adjacencies with routers 1 and two across the non-broadcast multiaccess (NBMA) frame relay link.

OSPF_multipoint_adjacencies.cap (16.3 KB)

Packets: 196 Avg Size: 69 bytes Duration: 277.1 sec
Data Rate: 0.38 Kbps Added: 14 Jun 2008 Downloads: 264

Routers 1 through 4 are configured to view the non-broadcast frame relay network as a point-to-multipoint topology. Adjacencies are formed without the need of a DR or BDR. Note that inverse ARP was used to dynamically learn the addresses of neighbors.

Packets: 93 Avg Size: 93 bytes Duration: 34.9 sec
Data Rate: 1.93 Kbps Added: 14 Jun 2008 Downloads: 214

The frame relay network between four routers is configured with point-to-point subinterfaces. No DR/BDR is required as all adjacencies are point-to-point. Capture perspective from R1.

OSPF_NBMA_adjacencies.cap (11.7 KB)

Packets: 99 Avg Size: 105 bytes Duration: 65.7 sec
Data Rate: 1.24 Kbps Added: 14 Jun 2008 Downloads: 208

Formation of OSPF adjacencies across a Non-broadcast Multiaccess (NBMA) frame relay topology. Neighbors have been manually specified on all routers, with R1 configured to become the DR. No BDR is present. Capture perspective from R1.
