5.15 IPv4 Layer 3 Configuration

IPv4 Layer 3 Overview
The ZXR10 2900E provides a few IPv4 layer-3 functions for the remote configuration and
management. To realize the remote access, an IP port must be configured on the switch.
If the IP port of the remote configuration host and that of the switch are not in the same
network segment, it is also necessary to configure the static route.
Static route is a simple unicast route protocol. The next-hop address to a destination
network segment is specified by a user, where next hop is also called gateway. Static route
involves destination address, destination address mask, next-hop address, and egress
interface. Destination address and destination address mask describe the destination
network information. The next-hop address and egress interface describe the way that
switch forwards destination packets.
The ZXR10 2900E allows adding and deleting the static ARP table. The ARP table records
mapping relationship between the IP address and the MAC address of each node in the
same network. When sending IP packets, the switch first checks whether the destination
IP address is in the same network segment. If yes, the switch checks whether there is a
peer end IP address and MAC address mapping entry in the ARP table.
1. If yes, the switch directly sends the IP packets to this MAC address.
2. If the MAC address corresponding to peer end IP address cannot be found in the ARP
table, an ARP Request broadcast packet will be sent to the network to query peer end
MAC address.
Entries of the ARP table on the switch are dynamic. Static ARP table entry needs to be
configured only when the connected host cannot respond the ARP Request.
Switch layer-3 configuration includes the following commands:
l Connectivity test
l
Layer 3 interface related configuration
l
ARP related configuration
l
Static route related configuration
The ZXR10 2900E series system supports the hardware routing function to increase IP
packets forwarding speed.
To configure the IPv4 layer-3 function, use the config router command to enter the layer-3
configuration mode first.
