AFAIK Local link addresses are addresses that can only talk to devices within its own subnet. Routers will not forward packets that come from local link addresses. Local link addresses are defined in the address block
Cisco says the following about the L code when using
show ip route. "Identifies that this is a link local route. Link local routes are automatically created when an interface is configured with an IP address and activated.".
Here's an example output of me using
show ip route in a packet tracer excercise.
10.0.0.0/8 is variably subnetted, 5 subnets, 3 masks C 10.10.1.0/30 is directly connected, Serial0/0/0 L 10.10.1.2/32 is directly connected, Serial0/0/0 C 10.10.1.8/30 is directly connected, Serial0/0/1 L 10.10.1.9/32 is directly connected, Serial0/0/1 D 10.10.1.16/28 [90/2170112] via 10.10.1.10, 02:09:24, Serial0/0/1
My question is: The ip adresses mentioned in
show ip route are the addresses of the NICs in each route, right? Then why do the L routes show ip addresses that arent in the address block previously mentioned? Clearly
10.10.1.2/32 is not in the address block
169.254.0.0/16. Or does local link have multiple definitions?
