# Display the BFD information of Router A. You can see that Router A has removed its neighbor
relationship with Router B and therefore no information is output.

Configuring IPv6 IS-IS MTR
Network requirements
As shown in Figure 96, enable IPv6 IS-IS MTR to make the routers perform route calculation separately in
IPv4 and IPv6 topologies.
