Configuration considerations

• MCT devices must obtain complete routing information using static routes for Layer 3 forwarding on

MCT VLANs.

• For MCT devices configured with VRRP or VRRP-E, track-port features can be enabled to track the

link status to the core devices so the VRRP or VRRP-E failover can be triggered.

• Configuring several Layer 3 features on VE of the session VLAN is not supported. If a VLAN is

already configured with multiple Layer 3 features, it cannot be made the session VLAN.

• Configuring UC/MC routing protocols and the IP follow feature on VEs of member VLANs is not

supported. If a VLAN is already configured in this way, it cannot be made a member VLAN.

• IPv6 configurations are not supported on VEs of session or member VLANs.

• Route-only ports cannot be used as CCEP or ICL ports.

• Global route-only configuration and MCT cluster configuration are mutually exclusive.

• Using MCT management interface IPs for a tunnel source is not supported.

• Configuring static and policy-based routes using VE on an MCT session VLAN is not supported.

• Configurations to redistribute connected routes will not advertise IP addresses on an MCT

management interface.

• IP addresses on the MCT management interface should not be used for BGP peers on neighboring

devices.

• IP addresses on the MCT management interface should not be used for static configurations on

neighboring devices.

• The track port feature should be used for VRRP switchover and controlling the validity of the SPF

feature.

• Up to 64 VRRP or VRRP-E instances are supported on an MCT cluster; however, with Jumbo

enabled, a maximum of 32 VRRP or VRRP-E instances is supported on an MCT cluster.

NOTE

To prevent unintended traffic forwarding by the CPU, Brocade recommends disabling ICMP redirect

globally when VRRP or VRRP-E is configured.

Layer 3 traffic forwarding behaviors

When one MCT device acts as a VRRP or VRRP-E master router and the peer device is the VRRP or

VRRP-E backup, the following behavior is observed:

• Packets sent to a VRRP-E virtual IP address are Layer 2-switched to the VRRP-E master device for

routing.

• The VRRP-E MAC address is learned by the other MCT device that acts as backup router.

• Both data traffic and VRRP-E control traffic received by the VRRP backup from an MCT client must

travel through the ICL, unless the short-path forwarding feature is enabled.

When both MCT devices act as the VRRP or VRRP-E backup routers, the following behavior is

observed:

• Packets sent to a VRRP-E virtual IP address is Layer 2-switched to the VRRP-E master router for

routing.

• The VRRP-E MAC address is learned by both MCT devices acting as backup routers.

• Both data traffic and VRRP-E control traffic travels through the links connecting them to the VRRP

master.
