OSPF_with_MD5_auth.cap (4.6 KB)
An OSPF adjacency is formed between two routers configured to use MD5 authentication.
OSPFv3_with_AH.cap (10.7 KB)
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)
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)
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)
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)
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)
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)
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)
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)
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)
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.
