Cisco Content Services Switch Routing and Bridging Configuration Guide
OL-4580-01
The CSS does not load balance TCP or UDP packets with IP options that are
destined to a VIP address. These packet types are dropped and the CSS returns an
ICMP destination/port unreachable error. This behavior exists regardless of the
state (enabled or disabled) of the ip record-route and ip source-route
commands.
The CSS, however, does respond to ICMP packets that are destined to a VIP
address. The CSS also responds to TCP or UDP packets that include IP options
that are destined to a local circuit address, or require that a routing decision be
made.
To disable the processing of frames with the record-route option (the default
behavior), enter:
(config)# no ip record-route
Configuring Box-to-Box Redundancy
Box-to-box redundancy provides chassis-level redundancy between two
identically configured CSSs. Refer to the Cisco Content Services Switch
Redundancy Guide for information about configuring box-to-box redundancy.
Use the ip redundancy command to enable box-to-box redundancy.
The CSS does not support simultaneous box-to-box redundancy and VIP or
interface redundancy configurations.
For example:
(config)# ip redundancy
To disable box-to-box redundancy, enter:
(config)# no ip redundancy
Configuring IP Equal-Cost Multipath
To set the equal-cost multipath (ECMP) selection algorithm and the preferred
reverse egress path, use the ip ecmp command. The CSS supports a maximum of
15 ECMP paths.
The syntax for this global configuration command is:
ip ecmp [address|no-prefer-ingress|roundrobin]
