A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment.
The DR for this segment would be the router with router ID 10.10.10.5.

The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment.
The DR for this segment would be the router with router ID 10.10.10.3.

Customers must use the same routing protocol as the service provider.

Customers belonging to the same VPRN service must use the same subnet.

For each VPRN, only one customer can be connected at each PE.

P routers run IPv4 only. PE routers run IPv4 only and exchange IPv6 routes using MP-BGP.

P routers run IPv6 only. PE routers run both IPv4 and IPv6 and exchange IPv4 routes using MP-BGP.

P routers run IPv6 only. PE routers run IPv6 only and exchange IPv4 routes using MP-BGP.

Policy changes are delayed until the peer router with the affected routes reboots.

Policy changes are delayed until route updates for affected BGP routes are received from peers.

Policy changes are delayed until the router reboots.

With the same method and attribute as 16-bit AS numbers.

Aggregation is not yet supported with 32-bit AS numbers.

By using a dummy value of 23456 in the 16-bit AS aggregator field. This value lets the router know it needs to read the 32-bit AS number that is contained in the nextTLV.

Assign an admin group to a MPLS interface.

Configure CSPF on the LSP.

Configure an "include" or "exclude" statement on the LSP path.

Router C sends the update to routers E and F only.

Router C sends the update to routers D, E and F.

Router C sends the update to routers A, B, E and F.

The customer's Layer 2 header is removed at the iLER.

Advertising external networks into IGP.

Exporting the networks associated with the external links of eBGP peers into BGP.

Optimizing BGP route table by exporting IGP routes into BGP.

A SAP is the subscriber's point of entry to the service network.

A SAP is created by specifying a physical port and an encapsulation type.

A SAP can only be created on a port configured as "access".

They reduce the number of SDPs that need to be configured.

They can be used to work around physical topologies that prevent a fully meshed deployment.

They can simplify the implementation of security policy enforcement and packet inspection.

RSVP uses downstream on demand label distribution mode.

LDP advertises label mappings to all peers for which it might be a next-hop for a given FEC.

RSVP distributes a label mapping for a FEC when it has been requested to do so.

The penultimate router will forward packets to the eLER, based on the IP header.

The eLER will receive packets with a top label value of 3.

The penultimate router will pop the top label from the packets.

Router R1forms an iBGP session with router R2, and an eBGP session with router R3.

Router R1forms iBGP sessions with routers R2 and R3.

Router R1forms eBGP sessions with routers R2 and R3.

Router R1 generates a type 5 LSA that is flooded through all OSPF areas.

Router R1 generates a type 7 LSA that is flooded through all OSPF areas.

Router R1 generates a type 5 LSA that is flooded through area 1. Router R2 generates a type 7 LSA that is flooded through areas 0 and 2.

A route target is used to distinguish to which VRF table a prefix belongs.

Multiple route targets can be part of a single MP-BGP update.

Route targets must be configured for VPRNs.

PE-1 requires T-LDP sessions to both ABR-1 and ABR-2.

ABR-1 requires T-LDP sessions to all ABRs in area 0.

PE-1 requires fast reroute enabled on all RSVP-TE LSPs.

Route reflectors require "n" iBGP sessions, where "n" is the number of BGP routers in the AS.

Route reflectors disable iBGP split horizon for all iBGP peers in the AS.

Route reflectors do not work in conjunction with confederations.
