BIERv6 OAM

Running Status Query

You can obtain the following information by running commands to learn about the running status of the BIERv6 network:

• BIERv6 BIRT
• BIERv6 BIFT (only in the diagnostic view)
• Configurations, such as BFR-prefixes and sub-domains

BIERv6 Ping

The BIERv6 ping function is used to check the connectivity of the BIERv6 network and check whether the network between the BFIR and one or more BFERs is normal. The process is described as follows:

1. A BIERv6 ping test is initiated on the BFIR, with BFR-IDs of one or more BFERs specified as a parameter. In this case, the BFIR constructs a BIERv6 ping request packet, sets the End.BIER SID of the next-hop device to the outer IPv6 destination address of the packet, and encapsulates the BFR-IDs of the BFERs as a BitString into the inner BIERv6 packet header.
2. The BIERv6 ping request packet is forwarded on the network according to the BIERv6 forwarding process.
3. After receiving the BIERv6 ping request packet, the BFERs each respond to the BFIR with a reply packet.
4. The BFIR summarizes the reply packets and displays information, including the reachability of a BFER and performance indicators such as the packet loss rate and delay. If no reply packet is received from a BFER within the timeout period, the result of the BFER's network connectivity check is Timeout.
