Variable-Length Subnet Mask Example
In the following example, a 14-bit subnet mask is used, leaving two bits of address space reserved for
serial line host addresses. There is sufficient host address space for two host endpoints on a
point-to-point serial link.
interface ethernet 0
ip address 172.17.1.1 255.255.255.0
! 8 bits of host address space reserved for ethernets
interface serial 0
ip address 172.17.254.1 255.255.255.252
! 2 bits of address space reserved for serial lines
! Router is configured for OSPF and assigned AS 1
router ospf 1
! Specifies the network directly connected to the router
network 172.17.0.0 0.0.255.255 area 0.0.0.0
Router# show key chain [name-of-chain]
