Chapter 6 Configuring the Internet Protocol
Forwarding IP Subnet Broadcast Addressed Frames
The options for this global configuration mode command are as follows:
• address - Choose among alternate paths based on IP addresses. For example:
(config)# ip ecmp address
• no-prefer-ingress - Do not prefer the ingress path of a flow for its reverse
egress path. By default, the ingress path for a flow is the preferred egress path.
This means that the preferred interface over which to reply to a client is the
interface on which the CSS originally received the request from the client.
For example:
(config)# ip ecmp no-prefer-ingress
To reset the ingress path of a flow for its preferred reverse egress path, enter:
(config)# no ip ecmp no-prefer-ingress
• roundrobin - Alternate between equal paths in roundrobin fashion. For
example:
(config)# ip ecmp roundrobin
Note The CSS applies the ECMP selection algorithm for non-TCP/UDP packets (for
example, ICMP) on a packet-by-packet basis. Multipath selection for TCP and
UDP is performed on a per-flow basis, and all packets for a particular flow take
the same path.
Forwarding IP Subnet Broadcast Addressed Frames
To enable the CSS to forward subnet broadcast addressed frames, use the
ip subnet-broadcast command.
For example:
(config)# ip subnet-broadcast
To disable forwarding of subnet broadcast addressed frames (the default
behavior), enter:
(config)# no ip subnet-broadcast
