Example

Example 147 IP route information

This example shows the gateway information for IP routes. A designation of "reject" means that

the IP traffic for that route is discarded. Blackhole/reject routes are added when a backup VR

becomes a Master and takes ownership of all VIPs. The blackhole/reject route ensures that routed

packets to the VIP are not forwarded through it. When virtual-ip-ping is enabled, the ping

packets to the VIP are responded to with ping replies.

HP Switch(config)# show ip route

Destination Gateway VLAN Type Sub-Type Metric Dist.

------------------ --------------- ---- --------- ---------- ---------- -----

Operational notes

• Jumbo frames are supported if they have been enabled for that VLAN. The VIP responds to

ping requests if they are not fragmented and are not larger than the MTU.

• Fragmented packets are not supported. All fragmented packets sent to a VIP are dropped and

no response or error is sent.

• All packets with IP options are dropped. Any ping options will work as long as they do not

change to IP options.

• ICMP requests other than echo requests are not supported.

• If there are errors in packets sent to a VIP, for example,"TTL Invalid," no ICMP error packet is

sent.
