Synopsis:
How Do I Verify a Route to the Virtual Router?

Problem:

Solution:

To verify a route for the virtual router, perform the following steps:

Open the Command Line Interface (CLI). For more information on how to open the CLI, go to Accessing the Command Line Interface Using Telnet.

Enter get route; press ENTER.

C - Connected, S - Static, A - Auto-Exported, I - Imported, R - RIP iB - IBGP, eB - EBGP, O - OSPF, E1 - OSPF external type 1 E2 - OSPF external type 2 trust-vr (2 entries)
----------------------------------------------------------------------------------------------------------------
ID     IP-Prefix                Interface          Gateway           P Pref         Mtr       Vsys
*2     192.168.1.0/24           eth1               0.0.0.0           C0             0         Root
*3     1.1.1.0/24               eth3               0.0.0.0           C0             0         Root

Unless the peer VPN gateway was directly connected to same subnet as this device, the NetScreen will not know where to send an outgoing packet destined for a subnet that is not the same as its own default gateway. It is a good practice on a NetScreen device to always specify a default route in the routing table in case the NetScreen does not know where to route a packet. This can be true even for directly connected devices on the subnet.

 To verify that there is a route to the destination IP, enter   get route ip [ip address of the destination ip];   press ENTER.

ns208-> get route ip 1.1.1.2
Destination Routes for 1.1.1.2
---------------------
trust-vr : => 1.1.1.1/24 (id=3) via 0.0.0.0 (vr: trust-vr)
Interface ethernet3 , metric 0


This indicates that there is a route in the trust-vr via a directly connected interface eth3.
