4 You can disable the VLT Proxy Gateway for a particular VLAN using an "Exclude-VLAN" conguration. The conguration has to be
done in both the VLT domains [C and D in VLT domain 1 and C1 and D1 in VLT domain 2].
Static Proxy Conguration Method
Dell(conf-vlt-domain)#proxy-gateway static
Dell(conf-vlt-domain-pxy-gw-static)#remote-mac-address 01:23:45:67:89:ab exclude-vlan 10
Dynamic Proxy Conguration Method
Dell(conf-vlt-domain)#proxy-gateway lldp
Dell(conf-vlt-domain-pxy-gw-lldp peer-domain-link port-channel 1 exclude-vlan 10
5 Packet duplication may happen with “Exclude-VLAN” conguration – Assume exclude-vlan (say VLAN 10) is congured in C and D
and in C1 and D1; If packets for VLAN 10 with C’s MAC address (C is in VLT domain 1) gets an L3 hit at C1 in VLT domain 2, they are
switched to both D1 (via ICL) and C via inter DC link. This may lead to packet duplication. If C’s MAC address is learned at C1, only (no
then) the packet is not have ooded (to D1) and only switched to C and thus packet duplication may be avoided.
6 With the existing hardware capabilities, you can only disable VLT Proxy Gateway only for 500 VLANs, using exclude-VLAN
conguration.
Conguring a Static VLT Proxy Gateway
You can congure a proxy gateway in VLT domains. A proxy gateway allows you to locally route the packets that are destined to an L3
endpoint of the other VLT domain.
To congure the static proxy gateway, perform the following:
1 Enable VLT on a switch, then congure a VLT domain and enter VLT-Domain Conguration mode.
CONFIGURATION mode
Dell(conf)#vlt domain domain-id
2 Congure the static proxy gateway.
VLT DOMAIN mode
Dell(conf-vlt-domain)#proxy-gateway static
3 You can congure the remote MAC address of a VLT peer for a static proxy gateway and exclude a VLAN or a range of VLANs from
proxy routing. This parameter is for a static proxy gateway conguration.
VLT DOMAIN PROXY GW STATIC mode
Dell(conf-vlt-domain-proxy-gw-static)#remote-mac-address mac-address exclude-vlan vlan-range
4 Display the VLT proxy gateway conguration.
EXEC mode
Dell#show vlt-proxy-gateway
Conguring an LLDP VLT Proxy Gateway
You can congure a proxy gateway in a VLT domain to locally route packets destined to a L3 endpoint in another VLT domain.
To congure an LLDP proxy gateway:
1 Enable VLT on a switch, then congure a VLT domain and enter VLT-Domain Conguration mode.
CONFIGURATION mode
Dell(conf)#vlt domain domain-id
2 Congure the LLDP proxy gateway.
VLT DOMAIN mode
Dell(conf-vlt-domain)#proxy-gateway lldp
