IPV6 OSPFv3 Notes
IPV6 OSPFv3
– Multicast FF02::5 – all routers
– Multicast FF02::6 – all DR routers
R1(config)# int s0/0
ipv6 ospf 1 area 0
ipv6 router ospf 1
ospf router-id 1.1.1.1
Summarization
– Inside routing mode
ipv6 router ospf 1
area 0 range <summary address/nm>
Default Routing
– Inside routing mode
ipv6 router ospf 1
default-information originate [ always | route-map <name> ]
Filtering
– Only distribute-list is supported
– Inter-area filtering is not supported
– Filtering is done on the local router between the database and the routing table
ipv6 router ospf
distribute-list prefix <name> in
Authentication
– OSPFv3 supports IPsec authentication
-> Authentication
-> MD5
-> SHA1 (Secure Hash Algorithm)
-> Encryption
-> DES
->3DES
-> AES
int s0/0
ipv6 ospf authentication ipsec spi 500 { md5 | sha1 } <password>
-> For MD5, password is 32 characters long
-> For SHA1, password is 40 characters long
ipv6 ospf encryption ipsec spi 500 { des | 3des | aes }
New LSAs and Changes
– LSA 8
-> Intra Area Prefixes
-> All connected networks of all routers within the area
– LSA 1
-> Only lists the neighbors / routers in the area
– LSA 9
-> Link LSA
-> It consists of the link-local address
-> Scope is link-local
