Both ASBR1 and ASBR2 advertise defaults into the network, expecting to have the capability to route to the Internet through BGP-learned routes. In this case, ASBR2 is already up, fully converged. However, if ASBR1 reloads, when it comes back up, OSPF is likely to converge faster than BGP. As a result, ASBR1 will advertise its [...]

Here are three ways you can easily add a connected network into OSPF.
Lets use g1/1 with an IP of 140.1.1.1/24
1. Use the network command
# router ospf 1
# network 140.1.1.1 0.0.0.0 area 0
2. Enable OSPF under the interface
# int g1/1
# ip ospf 1 area 0
3. Redistribute the network.
# route-map INT_G1_1 permit 10
# match interface g1/1
# router [...]

LAM is Cisco’s Local Area Mobility which is a way for mobile hosts to roam around the network. Although not very scalable, it does allow for a quick fix to certain network caveats. For example, say you have a server with an ip address of 10.10.10.100/24 which is in vlan 10. Now you are going [...]
