Description: This document describes how to filter the IPv4 routing table for relevant content (for example, when troubleshooting). Note: The CLI command show ipv4-route has no option to filter the routing table; instead, it is output in full. Requirements: · SSH client, e.g. PuTTY (download) Procedure: 1) Use a terminal program to open an SSH session on the LANCOM router. 2) The command show ipv4-fib allows the routing table to be filtered. In the following example, the routing table was filtered for VPN and shows the host route for a VPN client. root@1781VA:/ > show ipv4-fib @ VPN IPv4 Unicast FIB Rtg-Tag 0 Prefix Next-Hop Interface ID Type ---------------------------------------------------------------------------- 192.168.45.25/32 0.0.0.0 IKEV2C_0001 12 VPN Rtg-Tag 1 Prefix Next-Hop Interface ID Type ---------------------------------------------------------------------------- 192.168.45.25/32 0.0.0.0 IKEV2C_0001 12 VPN Rtg-Tag 2 Prefix Next-Hop Interface ID Type ---------------------------------------------------------------------------- 192.168.45.25/32 0.0.0.0 IKEV2C_0001 12 VPN 3) Another way to filter the routing table is to use the command ls Status/IP-Router/Act.-IP-Routing-Tab. The following example was also filtered for VPN and shows the host route for a VPN client. root@1781VA:/ > ls Status/IP-Router/Act.-IP-Routing-Tab./ @ vpn IP-Address IP-Netmask Rtg-tag Gateway Peer Distance Masquerade Type ===========================================------------------------------------------------------------------ 192.168.45.25 255.255.255.255 2 255.255.255.255 IKEV2C_0001 1 No VPN 192.168.45.25 255.255.255.255 1 255.255.255.255 IKEV2C_0001 1 No VPN 192.168.45.25 255.255.255.255 0 255.255.255.255 IKEV2C_0001 1 No VPN |
