| A | B |
|---|
| adjacency database | creates neighbor table |
| Ethernet MAC address | EUI-64 uses this to assign IPv6 address |
| Dijkstra's algorithm | OSPF uses this for SPF |
| open shortest path first | OSPF |
| backbone area | all routers part of this for single-area ospf |
| hello packet | used to maintain adjacency |
| link state update | packet to reply to LSR & request more info |
| dead interval | period of time before route dropped |
| designated router | elected to send LSAs |
| backup designated router | elected if DR fails |
| drother | router that isn't DR or BDR |
| router id | identifies router; used for DR election |
| router id, highest loopback, highest ip | order for DR election |
| wildcard mask | 0 matches, 1 ignores |
| passive interface | prevents transmitting updates, but receives updates |
| cost metric | OSPF uses this to measure routes |
| show ip route | displays IPv4 routing table |
| show interfaces | command to view interface bandwidth |
| show ip ospf neighbor | command to see adjacencies |
| show ip protocols | command to see process id, router id, networks, AD |
| show ip ospf | command to see process & router id |
| classless link state routing protocols | OSPFv2 & 3 are both ? |
| link local | IPv6 ospf uses these addresses |
| router configuration mode | use ipv6 router ospf [process id] |
| link state database | creates topology table |
| IP address and subnet mask | configured in software on PC for network participation |
| multicast | routers won't forward __ range 224.0.0.0-224.0.0.255 |
| private addresses | 10.1.1.1 & 172.22.2.2 |
| public addresses | majority of /8 block of IPv4 addresses |
| sixteen bits | there are __ __ in a hextet |
| unicast-routing | IPv6 __ __ enables router as IPv6 router |
| tracert | uses TTL values for each hop |
