When the port state transitions from Forwarding to Disking

Only when the port state transitions from Listening to Disccarding

When a topology change notification is received

NEW QUESTION 275
Host HW1 in the HW device network Wants to join a video conference, so what does that host do?

Sends an IGMPv2 membership report to the default router unicast of the local network

Sends a unicast IGMPv2 membership report to the RP

The IGMPv2 membership report is sent over multicast in the local network, and the multicast address carried in the IGMPv2 membership report is the multicast address that you want to join

The IGMPV2 membership report is sent over multicast in the local network, and the destination multicast address of the IGMPv2 membership report is “All PIM Routers” 224002 Multicast address

NEW QUESTION 276
The correct description of the extended features of ISIS is ?

When the amount of information in the Link State Protocol data packet PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP shards to carry more ISIS information.

ISIS can choose whether to authenticate incoming SNP and LSP packets

If there are other vendors’ devices on the network and do not support the LSP sharding function, the sharding expansion mode must be configured as Model-1, otherwise the message will not be recognized by other vendors’ devices.

After you enable the LSP shard extension feature of your router, you can use it without restarting the ISIS process.

NEW QUESTION 277
Regarding the BGP/MPLS IP VPN network architecture, what is the error described below?

sites can be accessed each other through vPNs, and a site can only belong to a VPN

P devices only need basic MPLS forwarding capabilities and do not maintain VPN-related information

BGP/MPLSIPVPN network architecture consists of CE (Customer Edge), PE (Provider Edge) and P (Provider), of which PE and P Is a carrier device, CE is BGP/MPLSIPVPN with Household equipment

Under normal circumstances, CE devices are not aware of the presence of VPN, and CE devices do not need to support MPLS MP-BGP, etc

NEW QUESTION 278
