4 You can disable the VLT Proxy Gateway for a particular VLAN using an "Exclude-VLAN" conguration. The conguration 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 Conguration 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 Conguration 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” conguration – Assume exclude-vlan (say VLAN 10) is congured 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

conguration.

Conguring a Static VLT Proxy Gateway

You can congure 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 congure the static proxy gateway, perform the following:

1 Enable VLT on a switch, then congure a VLT domain and enter VLT-Domain Conguration mode.

CONFIGURATION mode

Dell(conf)#vlt domain domain-id

2 Congure the static proxy gateway.

VLT DOMAIN mode

Dell(conf-vlt-domain)#proxy-gateway static

3 You can congure 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 conguration.

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 conguration.

EXEC mode

Dell#show vlt-proxy-gateway

Conguring an LLDP VLT Proxy Gateway

You can congure a proxy gateway in a VLT domain to locally route packets destined to a L3 endpoint in another VLT domain.

To congure an LLDP proxy gateway:
