When the group shake source sends IP6 multicast data, the TTL value of the packet is set to limit the transmission range of the group shake

There is a special field in the IPv6 multicast address that specifies the propagation range of multicast.

Multicast scope is just a concept of spreading scope, and there is no specific technical implementation.

During network configuration, the administrator uses the configuration command at the edge of the network to limit the multicast scope.

The hello packets sent at level-1 and Leve1-2 are both 5s

The hello packets sent at level-1 are sent at 5s interval

The level-2 hello packet send interval is 5s

The CSNP packet sending interval for this interface Level-2 is 5S

WRED can set different drop thresholds and packet loss rates for packets of different priority

When the flow exceeds the minimum threshold, WRED begins to discard all inlet flow (tail drop)

Avoid global synchronization by selectively dropping multiple TCP streams

Low-bandwidth traffic is easier to drop than high-bandwidth traffic

Users who connect to the same MCE but are not part of a VPN instance cannot access each other

The MCE vs. PE direction must have multiple physical links to achieve isolation between different VPN instances

MCE-enabled devices can access multiple VPI instances in BGP/RPLS IPVPN applications, reducing user network equipment investment

On the MCE device, you need to create their own routing tables for different VPNs and bind to the corresponding interface
