A Sample VLAN Topology

Chapter 7

# zhp2 does not have an assigned IP address.

sibling_addresses: zhp1 = 10.35.50.41, 10.35.50.42 netmask 255.0.0.0;

sibling_addresses: zhp3 = 192.168.0.43, 192.168.0.44 netmask 255.255.255.0;

# The virtual address spans the sibling group, giving hosts and routers

# a single point to connect to, or a single point to use as, a router. A

# virtual address should not be specified for the interconnect interface.

# For pure layer 2 failover, no virtual address is required.

# Note: ISL (zhp3) does not need a virtual address.

vrrp_virtual_address: zhp1 = 10.35.50.43 netmask 255.0.0.0;

# Define the interconnect VLAN interface. This VLAN allows network traffic

# to flow to/from the master Switch Blade to/from the backup switch.

interconnect: zhp3;

# Port definitions:

# Define what ports are configured for failover. Specifications

# can be by zhp or zre name. The zhp name is a shortcut to specify

# the entire port group associated with that interface. In the end,

# these definitions are on a port by port basis. Note: zhp and

# zre names cannot be mixed on the same line.

RAINlink: zre13, zre12, zre0..11, zre14..21;

############################# Special Modes #############################

# VRRP modes:

# The block_crossconnect mode causes the equivalent of STP blocking on the

# crossconnect ports of the VRRP Backup. The block_crossconnect mode is

# meant as a replacement for STP, however, the Switch Blades connected to the

# crossconnect ports must be Ethernet Switch Blades running Surviving Part-

ner.

# The RAINlink_xmit_on_failover mode requires that the OpenNode blades

# connected to RAINlink ports transmit a packet when failing over, so that

# The Layer 2 tables will learn the new port/MACaddress relationship. An

# example is the SNAP_BCAST_MODE in RAINlink or a gratuitous ARP. If

# using RAINlink_xmit_on_failover, it is recommended to use the -i D option

# to zl3d.

vrrp_mode: RAINlink_xmit_on_failover;
