GRE IP tunnel

Configuring ECMP for routes through an IP GRE tunnel
If multiple routes are using IP GRE tunnels to a destination, packets are automatically
load-balanced between tunnels. This feature allows for load distribution of traffic among the
available IP GRE tunnels. If the routes to a destination are both normal IP routes and routes
through IP GRE tunnels, ECMP is not enabled.
CAM restrictions
CAMs are partitioned on a Brocade device by a variety of profiles that you can select for your
specific application.
To implement a CAM partition for a GRE tunnel, enter a command such as the following.
NOTE
You must reload your Brocade device for this command to take effect.
Brocade(config)# cam-partition profile ipv4
Syntax: [no] cam-partition profile [ ipv4 | ipv4-ipv6 | ipv4-vpls | ipv4-vpn | ipv6 | l2-metro |
l2-metro-2 | mpls-l3vpn | mpls-l3vpn-2 | mpls-vpls | mpls-vpls-2 | mpls-vpn-vpls |
multi-service | multi-service-2 | multi-service-3 | multi-service-4]
The ipv4 parameter adjusts the CAM partitions, as described in the tables below to optimize the
device for IPv4 applications.
The ipv4-ipv6 parameter adjusts the CAM partitions, as described in the tables below to optimize
the device for IPv4 and IPv6 dual stack applications.
The ipv4-vpls parameter adjusts the CAM partitions, as described in the tables below to optimize
the device for IPv4 and MPLS VPLS applications.
The ipv4-vpn parameter adjusts the CAM partitions, as described in the tables below to optimize
the device for IPv4 and MPLS Layer-3 VPN applications.
The ipv6 parameter adjusts the CAM partitions, as described in the tables below to optimize the
device for IPv6 applications.
The l2-metro parameter adjusts the CAM partitions, as described in the tables below to optimize
the device for Layer 2 Metro applications.
The l2-metro-2 parameter provides another alternative to l2-metro to optimize the device for Layer
2 Metro applications. It adjusts the CAM partitions, as described in the tables below for the
Brocade NetIron XMR.
The mpls-l3vpn parameter adjusts the CAM partitions, as described in the tables below, to optimize
the device for Layer 3, BGP or MPLS VPN applications.
The mpls-l3vpn-2 parameter provides another alternative to mpls-l3vpn to optimize the device for
Layer 3, BGP or MPLS VPN applications.
The mpls-vpls parameter adjusts the CAM partitions, as described in the tables below to optimize
the device for MPLS VPLS applications.
The mpls-vpls-2 parameter provides another alternative to mpls-vpls to optimize the device for
MPLS VPLS applications. It adjusts the CAM partitions, as described in the tables below.
The mpls-vpn-vpls parameter adjusts the CAM partitions, as described in the tables below, to
optimize the device for MPLS Layer-3 and Layer-2 VPN applications.
The multi-service parameter adjusts the CAM partitions, as described in the tables below to
optimize the device for Multi-Service applications.
