IP routing 15 A subnet address is created by increasing the netw ork por tion to include a subnet address, thus decreasing the host por tion of the IP address. For e xample, in the address 128.32.10.0, the network por tion is 128.32, while the subnet is f ound in the first octet of the host por tion (10). A subnet mask is applied to the IP address[...]

16 An Introduction to IP Routing Protocols V ariable-length subnet masking (VLSM) is the ability to divide an intranet into pieces that match network requirements. Routing is based on the longest subnet mask or network that matches. IP routing using VLANs The Nor tel Ether net Routing Switch 5500 Ser ies suppor ts wire-speed IP routing between vir [...]

IP routing 17 As with any IP address, vir tual router interface addresses are also used for de vice management. For management ov er IP , any vir tual router interf ace IP address can be used to access the s witch as long as routing is enab led.
