Implementing Cisco Service Provider Advanced Routing Solutions (SPRI) Practice Test

Skills this practice test covers

• Troubleshoot OSPF multiarea and IS-IS multilevel routing, including summarization, for IPv4 and IPv6.
• Scale BGP with route reflectors and confederations, and secure it with TTL security and maximum prefix limits.
• Cut convergence time with BFD, nonstop forwarding, BGP PIC and loop-free alternates.
• Write route policies in RPL and in route maps, then troubleshoot route filtering and traffic steering.
• Set up PIM-SM rendezvous points, SSM and MSDP, and troubleshoot multicast across domains.
• Move an LDP core to segment routing with TI-LFA, SR traffic engineering and SRv6.

About the 300-510 exam

How to earn the certification

Earns

Cisco Certified Specialist - Service Provider Advanced Routing ImplementationProfessional (concentration exam)

The certification is valid for three years.

Before

• 200-301 Cisco Certified Network Associate (CCNA)

  Recommended, not required. It covers the routing basics that SPRI takes to provider scale.

How to prepare for 300-510

1. 1

   Build an IOS XR and IOS XE lab

   Use Cisco Modeling Labs or a similar lab, so that RPL and route maps can be tried side by side. Start with IS-IS and OSPF, then add iBGP with route reflectors.

2. 2

   Leak routes between IS-IS levels

   Unicast Routing is the largest domain. Move prefixes between IS-IS Level 1 and Level 2 and between OSPF areas, with and without summarization, and read the routing table after each change.

3. 3

   Rewrite route maps as RPL

   Turn familiar route maps into RPL policies with prefix sets, community sets and parameters. Attach them to BGP and IGP routes and check which routes pass.

4. 4

   Migrate a core from LDP to SR

   Run segment routing next to LDP, use SR prefer and a mapping server, then add TI-LFA. Finish with an SR policy that traffic joins through automated steering by color.

5. 5

   Time the full SPRI practice test

   Take the 300-510 practice test domain by domain in Study Mode, then as a full run in Timed Mode. Rebuild every missed multicast or policy case in the lab before the next run.

Who 300-510 is for

• Engineers who run the IS-IS, BGP and MPLS core of a service provider or carrier network.
• CCNP Service Provider candidates who pair SPCOR with a routing concentration exam.
• Network architects who plan a move from LDP to segment routing or SRv6.

Typical job titles: Network engineer · Service provider engineer · Network architect · Systems engineer · Technical solutions architect

300-510 glossary

20 terms from the exam objectives and the vendor's official material, each defined in a sentence.

Anycast RP

Several rendezvous points that share one address, so routers use the nearest one and another takes over if it fails.

BGP confederations

A way to split one autonomous system into smaller sub-autonomous systems that peer with each other, which shrinks the iBGP mesh.

BGP free core

A design in which only edge routers run BGP, while core routers forward on MPLS labels without learning external routes.

BGP PIC

BGP Prefix Independent Convergence: precomputed backup paths that let a router move many prefixes to a new next hop at once after a failure.

Bidirectional forwarding detection

A light hello protocol that detects a failed link or neighbor quickly and tells the routing protocols to react.

Flexible algorithm

A segment routing feature that adds custom path calculations, such as lowest delay or avoiding certain links, next to the normal shortest path.

FlowSpec

A BGP extension that sends traffic filter rules, such as drop or rate-limit actions, to many routers at once.

IPv6 provider edge (6PE)

A way to carry IPv6 traffic across an IPv4 MPLS core, with BGP exchanging IPv6 prefixes and labels between provider edge routers.

MAP-T

Mapping of Address and Port using Translation: a stateless method that carries customers' IPv4 traffic across an IPv6-only network by translating it.

Mapping server

A segment routing function that advertises prefix segments on behalf of routers that cannot, used while parts of the network still run LDP.

MLDP

Multipoint LDP: an extension of LDP that builds point-to-multipoint label switched paths to carry multicast across an MPLS core.

Multicast Source Discovery Protocol (MSDP)

A protocol that tells rendezvous points in other PIM-SM domains about active sources, so receivers can join sources outside their own domain.

Route dampening

A BGP feature that suppresses a route that keeps flapping until the route has been stable for a set time.

Route reflectors

BGP routers that pass routes learned from internal peers on to other internal peers, so the network needs no full mesh of iBGP sessions.

Routing policy language (RPL)

The IOS XR language for route policies, built from named sets and if-then statements. Route maps do the same job on IOS.

Source Specific Multicast (SSM)

A multicast model in which receivers ask for traffic from one known source, so no rendezvous point is needed.

SRGB

Segment Routing Global Block: the label range that a router reserves for global segments, such as prefix segments.

SRLG

Shared Risk Link Group: links that can fail together, for example because they share one fiber path, so traffic engineering can keep paths apart.

SRv6

Segment routing over IPv6: each segment is an IPv6 address, and the packet carries its list of segments in IPv6 headers.

Topology-Independent Loop-Free Alternate (TI-LFA)

A segment routing fast reroute method that precomputes a loop-free backup path for any topology and uses it right after a failure.
