The
ip-addr
parameter displays the route to the specified IP address.
The
ip-mask
parameter lets you specify a network mask or, if you prefer CIDR format, the number of bits in the network mask. If you use
CIDR format, enter a forward slash immediately after the IP address, then enter the number of mask bits (for example: 10.157.22.0/24
for 10.157.22.0 255.255.255.0).
The
longer
parameter applies only when you specify an IP address and mask. This option displays only the routes for the specified IP
address and mask. Refer to the following example.
The
none-bgp
parameter displays only the routes that did not come from BGP4.
The
num
option display the route table entry whose row number corresponds to the number you specify. For example, if you want to
display the tenth row in the table, enter "10".
The
bgp
option displays the BGP4 routes.
The
direct
option displays only the IP routes that are directly attached to the Layer 3 switch.
The
ospf
option displays the OSPF routes.
The
rip
option displays the RIP routes.
The
static
option displays only the static IP routes.
The
default
routes are displayed first.
