Displayed information
Explanation
C –connected
Direct route, namely the segment directly
connected with the layer 3 switch
S –static
Static route, the route manually configured
by users
R - RIP derived
RIP route, acquired by layer 3 switch
through the RIP protocol.
O - OSPF derived
OSPF route, acquired by layer 3 switch
through the OSPF protocol
A- OSPF ASE
Route introduced by OSPF
B- BGP derived
BGP route, acquired by the BGP protocol.
Destination
Target network
Mask
Target network mask
Nexthop
Next-hop IP address
Interface
Next-hop pass-by layer 3 swtich interfaces
Preference
Route priority. If other types of route to the
target network exists, the kernel route will
only shows those with high priority.
