Which three statements are correct about OSPF route summarization? (Choose three.)

  1. A flat addressing scheme is required in order to summarize OSPF routes.
  2. OSPF internal routes can be summarized only at the ABRs.
  3. OSPF type 5 external routes can be summarized only at the ASBRs.
  4. Route summarization can lead to a more stable network.

Which option is true about routing control while using routing protocols in a DMVPN network (or any GRE-over-IPsec network)?

  1. Routing of the data plane traffic should be carried out by means of the GRE tunnel and a separate routing instance should be used to handle routing of the crypto endpoints.
  2. The control plane traffic for the crypto endpoints should be routed through the GRE tunnel; the control plane traffic for the data plane traffic should travel via the transport network.
  3. If the network is a private MPLS network, the routing for the data plane traffic and the crypto endpoints should be run outside of the GRE tunnel.
  4. The routing used to establish the crypto endpoints should include information for the data networks behind the endpoints.

Answer(s): A



Study the following exhibit carefully. A service provider with a multi-area OSPF environment would like to deploy MPLS TE tunnels among PE routers across area boundaries. Configure the LSPs with bandwidth constraints and explicit loose route hops as indicated by the arrows in the following path: PE1 -> ABR1 -> ABR2 -> PE2Which two items identify devices that will execute constraint-based SPF in order to set up LSP from PE1 to PE2? (Choose two.)

  1. PE1
  2. All routers in Area 1
  3. All ABRs
  4. All routers in Area 2

Answer(s): A,C



VLAN Tagging, also known as Frame Tagging, is a method developed by Cisco to help identify packets travelling through trunk links. When an Ethernet frame traverses a trunk link, a special VLAN tag is added to the frame and sent across the trunk link .How does ERS use the VLAN tag?

  1. Provide service internetworking
  2. Support transparency for Layer 2 frames
  3. Indicate destination as a connection identifier
  4. Map to the DLCI in service internetworking

Answer(s): C
