2 OSPFv3 2
3 OSPFv2 Latest revision is RFC 2328 April 1998 OSPF uses a 2 level hierarchical model SPF calculation is performed independently for each area Typically faster convergence than DVRPs Relatively low steady state bandwidth requirements 3
4 OSPFv3 overview OSPFv3 is OSPF for IPv6 Based on OSPFv2, with enhancements Distributes IPv6 prefixes Runs directly over IPv6 Ships-in-the-night with OSPFv2 4
5 Similarities to OSPFv2 Same basic packet types Hello, DBD, LSR, LSU, LSA Same mechanisms for neighbor discovery and adjacency formation Same interface types P2P, P2MP, Broadcast, NBMA, Virtual Same LSA flooding and ageing Almost same LSA types 5
6 Differences from OSPFv2 Runs over a link, not a subnet Multiple instances per link Topology not IPv6-specific Router ID Link ID Standard authentication mechanisms Uses link local addresses Generalized flooding scope Two new LSA types 6
7 LSA Type Review LSA function code LSA type Router-LSA Network-LSA Inter-Area-Prefix-LSA Inter-Area-Router-LSA AS-External-LSA Group-membership-LSA Type-7-LSA Link-LSA Intra-Area-Prefix-LSA x2001 0x2002 0x2003 0x2004 0x4005 0x2006 0x2007 0x0008 0x2009 U S2 S1 LSA function code 7
8 New LSA Type Field U S2 S1 LSA function code U: indicates how the LSA should be handled by a router that does not recognize the LSA's function code S2,S1: indicate the flooding scope of the LSA (link local, area, AS local) Each LSA function code also implies a specific setting for the U, S2, and S1 bits 8
9 Link LSA A link LSA per link Link local scope flooding on the link they are associated with Provide router link local address List all IPv6 prefixes attached to the link Assert a collection of option bits for the Router-LSA 9
10 Link LSA structure Rtr priority Options Link local Interface address # prefixes Prefix Lgth PrefOptions 0 Address Prefix Prefix Lgth Options 0 Address Prefix 10
11 Link LSA of R3 For LAN1 R3#show ip ospf database link DR Link (Type-8) Link States (Area 0) LS age: 1936 Options: (V6-Bit E-Bit R-bit DC-Bit) LS Type: Link-LSA (Interface: FastEthernet0/0) Link State ID: 3 (Interface ID) Advertising Router: LS Seq Number: E Checksum: 0xD7B3 Length: 68 Router Priority: 1 Link Local Address: FE80::204:C1FF:FEDB:2FA0 Number of Prefixes: 2 Prefix Address: 3FFE:FFFF:1:: Your interface Prefix Length: 64, Options: None Prefix Address: 3FFE:FFFF:1:: Remote interface R1 R2 1 R3 R4 Area
12 Intra-area prefix LSA Multiple LSA with the different Link State ID Area flooding scope 1- associate prefix with transit network referencing a Network-LSA 2- associate prefix with a router or a stub referencing a Router-LSA 12

16 Configuring OSPFv3 on Cisco IOS Very similar to OSPFv2 mostly a matter of prefixing existing Interface and Exec mode commands with ipv6 Interfaces configured directly replaces network command Native IPv6 router mode not a sub-mode of router ospf 16
17 Configuration modes in OSPFv3 Entering router mode [no] ipv6 router ospf <process ID> Entering interface mode [no] ipv6 ospf <process ID> area <area ID> Exec mode [no] show ipv6 ospf [<process ID>] clear ipv6 ospf [<process ID>] 17
18 Cisco IOS OSPFv3 specific attributes Configuring area range [no] area <area ID> range <prefix>/<prefix length> Showing new LSAs show ipv6 ospf [<process ID>] database link show ipv6 ospf [<process ID>] database prefix 18
19 OSPFv3 debug commands Adjacency is not coming up [no] debug ipv6 ospf adj [no] debug ipv6 ospf hello SPF is running constantly [no] debug ipv6 ospf spf [no] debug ipv6 ospf flooding [no] debug ipv6 ospf events [no] debug ipv6 ospf lsa-generation [no] debug ipv6 ospf database-timer General purpose [no] debug ipv6 ospf packets [no] debug ipv6 ospf retransmission [no] debug ipv6 ospf tree 19
