How to configure ip-prefix-list 0.0.0.0./0?
Example of prefix-list configuration is shown below. The configuration allows route reception by default.
esr(config)# ip prefix-list eltex
esr(config-pl)# permit default-route
Problem of asynchronous traffic transmission is occurred
In case of asynchronous routing, Firewall will forbid 'incorrect' ingress traffic (which does not open new
connection and does not belong any established connection) for security reasons.
Allowing rule in Firewall does not solve the problem.
Firewall should be disabled on the ingress interface.
esr(config-if-gi)# ip firewall disable
How to save the local copy of the router configuration?
If you need to copy the current running or candidate configuration on the router itself, you can use the copy
command specifying 'system:running-config' or 'system:candidate-config' as the copy source, and the file in
the 'flash:data/' section as the copy destination.
esr# copy system:candidate-config flash:data/temp.txt
Also, it is possible to copy previously saved configuration files (automatically from the flash:backup/ section
or manually from the flash:data/ section) to the candidate configuration:
esr# copy flash:data/temp.txt system:candidate-config
esr# copy flash:backup/config_20190918_164455 system:candidate-config
