Configuring VRRP
This section presents two sample VRRP configurations:
■
A basic VRRP configuration with one virtual router
A symmetrical VRRP configuration with two virtual routers
■
The 8100fl switch is limited to up to fifteen unique virtual router configurations
per interface (physical port, LAG, or VLAN). The virtual router ID (VRID) for
each instance must be numbered within the range of <1-15>. VRIDs can be
re-used, but not on the same interface.
Basic VRRP Configuration
Figure 16-1
shows a basic VRRP configuration with a single virtual router
enabled on VLAN 15. Routers R1 and R2 are both configured with one virtual
router (VRID=1). Router R1 serves as the Master and Router R2 serves as the
Backup. The four end hosts (H1 - H4) are configured to use 10.0.0.1/24 as the
default route. IP address 10.0.0.1/24 is associated with virtual router VRID=1.
