node to choose a different VLAN or IP route to reach the PIM neighbor. This can result in issues with
multicast route syncing between peers.
• Both VLT peers require symmetric Layer 2 and Layer 3 configurations on both VLT peers for any
spanned VLAN.
• For optimal performance, configure the VLT VLAN routing metrics to prefer VLT VLAN interfaces over
non-VLT VLAN interfaces.
• When using factory default settings on a new switch deployed as a VLT node, packet loss may occur
due to the requirement that all ports must be open.
• ECMP is not compatible on VLT nodes using VLT multicast. You must use a single VLAN.
Configuring VLT Multicast
To enable and configure VLT multicast, follow these steps.
1.
Enable VLT on a switch, then configure a VLT domain and enter VLT-domain configuration mode.
CONFIGURATION mode
vlt domain
domain-id
2.
Enable peer-routing.
VLT DOMAIN mode
peer-routing
3.
Configure the multicast peer-routing timeout.
VLT DOMAIN mode
multicast peer-routing—timeout
value
value
: Specify a value (in seconds) from 1 to 1200.
4.
Configure a PIM-SM compatible VLT node as a designated router (DR). For more information, refer to
Configuring a Designated Router
.
5.
Configure a PIM-enabled external neighboring router as a rendezvous point (RP). For more
information, refer to
Configuring a Static Rendezvous Point
.
6.
Configure the VLT VLAN routing metrics to prefer VLT VLAN interfaces over non-VLT VLAN
interfaces. For more information, refer to
Classify Traffic
.
7.
Configure symmetrical Layer 2 and Layer 3 configurations on both VLT peers for any spanned VLAN.
Non-VLT ARP Sync
ARP entries (including ND entries) learned on other ports are synced with the VLT peer to support station
move scenarios.
NOTE: ARP entries learned on non-VLT, non-spanned VLANs are not synced with VLT peers.
RSTP Configuration
RSTP is supported in a VLT domain.
Before you configure VLT on peer switches, configure RSTP in the network. RSTP is required for initial
loop prevention during the VLT startup phase. You may also use RSTP for loop prevention in the network
outside of the VLT port channel. For information about how to configure RSTP,
Rapid Spanning Tree
Protocol (RSTP)
