Cisco::ShowIPRoute::Parser - parse Cisco 'show ip route' command
use Cisco::ShowIPRoute::Parser; # Router.log holds the output from 'show ip route' my $log = 'Router.log'; my $r = new Cisco::ShowIPRoute::Parser($log); my $dest = '10.159.25.44'; my @routes = $r->getroutes($dest); print "@routes\n";
This File contains the encapsulation of Raj's route parser. It will parse the output from a Cisco 'show ip route' command and return all the routes to a specified IP address.
When collecting the routes please ensure it is in decimal format. This can be enabled by doing the following at the router prompt:
term len 0 terminal ip netmask-format decimal show ip route
the log file as a string
Handle to our object.
Define some initial states and open the log file that is to be used when parsing routes
the IP address to get the routes for as a string
An array of IP addresses, or "directly connected..." messages.
Or a null list if no routes found
We call ipRouteCheck() and routeIterate() to find all the routes. This is the main interface. You shouldn't need any other methods.
It is highly possible there are bugs. But we don't think so. We have tested this over 4000 routers and pulled routes across this network often. Whenever we think the code is wrong we invariably find we have a network routing problems.
