Packets: 34 Avg Size: 120 bytes Duration: 63.5 sec
Data Rate: 0.50 Kbps Added: 10 Oct 2008 Downloads: 390

An OSPF adjacency is formed between two routers configured to use MD5 authentication.

OSPFv3_with_AH.cap (10.7 KB)

Packets: 61 Avg Size: 164 bytes Duration: 170.0 sec
Data Rate: 0.46 Kbps Added: 31 Aug 2008 Downloads: 292

The adjacency between R1 and R2 in the 2001:db8:0:12::/64 subnet is configured with IPsec AH authentication. Note the inclusion of an IPsec AH header immediately following the IPv6 header of each OSPF packet.

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: 213

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
Data Rate: 1.02 Kbps Added: 31 Aug 2008 Downloads: 200

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

OSPFv3_broadcast_adjacency.cap (5.4 KB)

Packets: 38 Avg Size: 129 bytes Duration: 70.0 sec
Data Rate: 0.55 Kbps Added: 31 Aug 2008 Downloads: 209

Routers 1 and 2 form an OSPFv3 adjacency across their common Ethernet link (2001:db8:0:12::/64).

OSPF_type7_LSA.cap (3.6 KB)

Packets: 25 Avg Size: 130 bytes Duration: 32.0 sec
Data Rate: 0.79 Kbps Added: 17 Jun 2008 Downloads: 154

Area 10 is configured as a not-so-stubby area (NSSA). The capture records the adjacency formed between routers 2 and 3. The link state update in packet #11 includes several type 7 LSAs from R2. Capture perspective from R3's 10.0.10.1 interface.

OSPF_LSA_types.cap (4.0 KB)

Packets: 30 Avg Size: 120 bytes Duration: 62.9 sec
Data Rate: 0.45 Kbps Added: 17 Jun 2008 Downloads: 200

Capture of adjacency formation between OSPF routers 4 and 5 in area 20. Packet #12 contains LSAs of types 1, 2, 3, 4, and 5.

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: 187

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.

OSPF_broadcast_adjacencies.cap (8.4 KB)

Packets: 74 Avg Size: 100 bytes Duration: 95.2 sec
Data Rate: 0.61 Kbps Added: 14 Jun 2008 Downloads: 206

Three routers form OSPF adjacencies across a broadcast segment. All interface priorities are left default, so R3 (with the highest router ID) becomes the DR, and R2 (with the next-highest router ID) becomes the BDR. Capture perspective from R1.

OSPF_point-to-point_adjacencies.cap (9.9 KB)

Packets: 93 Avg Size: 93 bytes Duration: 34.9 sec
Data Rate: 1.93 Kbps Added: 14 Jun 2008 Downloads: 153

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: 142

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.
