Hi..
Sorry, I need a few more questions to verify whether my understanding on
loopback is correct or not? Pls answer it.
1) If I have two router A (loopback=192.168.0.1/32) and B
(loopback192.168.0.2/32), Router A's S1 int 100.100.100.1/24 is connected to
Router B's S1 100.100.100.2/24. There are no more other connection. If S1
of B is down. Can I still telnet from A to B using B's loopback address.
2) If Router A and B have another connection. Router A's S2 int
100.200.100.1/24 is connected to Router B's S2 100.200.100.2/24. If S1 of B
is down. Can I still telnet from A to B using B's loopback address?
3) If Router A doesn't have loopback int configured. Can we still telnet
from A to B?
4) Whether the loopback IP address need to be in order or same network? Let
say Router A's loopback is 192.168.0.1/32 and Router B's loopback is
20.20.20.1/8. Can we still telnet from A to B?
5) If I configured A's loopback IP to be 192.168.0.1/24, can we still
configured B's loopback to be 192.168.0.2/24? Note: there are in same
network.
