Extended Router Information

IPv6 sFlow sampled packets include the following extended router information:

• IP address of the next-hop router
• Outgoing VLAN ID
• Source IP address prefix length
• Destination IP address prefix length

Note that in IPv6 devices, the prefix lengths of the source and destination IP addresses are collected if BGP is configured and the route lookup is completed. In IPv4 devices, this information is collected only if BGP is configured on the devices.
