NEW QUESTION 1
On Cisco IOS and IOS XE Layer 3 MPLS VPN implementations, when redistributing the customer RIP routes into MP- BGP, the RIP metric is copied into which BGP attribute?
Answer: C
Explanation: https://supportforums.cisco.com/thread/191993
Use the red bgp <asn> metric transparent command to preserve the RIP metrics.
When RIP routes are redistributed into BGP, the route metric is stored in the BGP MED value. When BGP routes are redistributed into RIP, and the transparent keyword used, the MED value is copied back as the RIP metric. Without the transparent keyword, the metric value specified is applied to all the routes.
NEW QUESTION 2
Refer to the exhibit.
Given the output shown, which two statements are true? {Choose two.}
Answer: AC
NEW QUESTION 3
A service provider wants to scale MAC address advertisements in its next generation E-LAN and E-TREE designs. Which technology can be used in the service provider cloud to reach this goal?
Answer: A
NEW QUESTION 4
Which three security features can be implemented on PEs inside a Cisco IOS XR VPLS environment? {Choose three.}
Answer: ABC
NEW QUESTION 5
Refer to the partial Cisco IOS XR PE router configuration exhibit for supporting a Layer 3 MPLS VPN customer using BGP as the CE-to-PE routing protocol.
The service provider AS number is 64500, the customer AS number is 64501, and the customer CE router is 10.1.1.1. What is missing in the configuration?
Answer: A
Explanation: http://www.cisco.com/en/US/docs/ios/12_2sr/12_2sra/feature/guide/srbgprid.html Route Distinguisher
A router distinguisher {RD} creates routing and forwarding tables and specifies the default route distinguisher for a VPN. The RD is added to the beginning of an IPv4 prefix to change it into a globally unique VPN-IPv4 prefix. An RD can be composed in one of two ways: with an autonomous system number and an arbitrary number or with an IP address and an arbitrary number. You can enter an RD in either of these formats:
•Enter a 16-bit autonomous system number, a colon, and a 32-bit number. For example: 45000:3
•Enter a 32-bit IP address, a colon, and a 16-bit number. For example: 192.168.10.15:1
NEW QUESTION 6
Refer to the exhibit.
PE1 and PE2 are advertising the same subnet 196.168.10.0/24 to PE3. Which PE advertised subnet is installed at PE3 BGP table?
Answer: D
NEW QUESTION 7
Which BGP extended community is used to control the distribution of VPN routing information and to identify routers that may receive a set of routes that carry the community?
Answer: B
Explanation: http://blog.initialdraft.com/archives/1537/
Route Target is a 64-bits BGP community used for tagging prefixes. When exporting prefixes from the VRF, we add to the prefixes a Route-Target community, so when the PE in the remote site has to import prefixes into the VRF, it can easily identify which prefixes to import.
NEW QUESTION 8
A customer has two sites over an MPLS cloud with Ethernet connections and requires one STP domain to be transparent over the MPLS provider. Which label-switching technology can the provider use without getting involved in learning the customer MAC addresses?
Answer: B
NEW QUESTION 9
Which protocol is used to hide customer VLANs inside the provider backbone network?
Answer: C
NEW QUESTION 10
Refer to the partial Cisco IOS XR PE router VRF configuration exhibit.
To implement a central-service VPN supporting both customer1 and customer2, what will be the required corresponding VRF configuration on the central-service-server PE router?
Answer: A
NEW QUESTION 11
A customer wants two separated sites to be connected via a pseudo-wire. Which solution provides the simplest implementation?
Answer: A
NEW QUESTION 12
When troubleshooting EoMPLS configuration problems, which three parameters must match between the two ends of the pseudowire configurations? {Choose three.}
Answer: ABC
Explanation: Provisioning an AToM Static Pseudowire
In this configuration task, you use options in the xconnect Ethernet interface configuration command to specify a static connection, and mpls commands in xconnect mode to statically set the following pseudowire parameters:
•Set the local and remote pseudowire labels
•Enable or disable sending the MPLS control word
Haven't been able to find where MTU Must match
NEW QUESTION 13
A customer requests Internet through its MPLS provider. Which Internet design model guarantees maximum security and easier provisioning?
Answer: C
NEW QUESTION 14
When implementing VPLS on Cisco IOS XR routers, the VPLS PW neighbors can be statically defined under which configuration mode?
Answer: C
Explanation:
NEW QUESTION 15
Which Layer 2 encapsulations can AToM solution support with interworking IP feature enable?
Answer: A
NEW QUESTION 16
Which VPN technology is an example of a full-mesh VPN?
Answer: D
