Cisco SPRI 300-510 case studies
Cisco SPRI 300-510 · Put your knowledge to work in context.
The Cisco 300-510 SPRI exam is a concentration exam in Cisco's service provider certification track, aimed at engineers who design and operate SP networks built on OSPF, IS-IS, BGP, MPLS, and multicast. It suits network engineers, NOC and design staff, and CCNP Service Provider candidates who already configure routers daily and need to prove depth in implementation and troubleshooting rather than basic configuration. The exam tests practical judgment: tuning IGP metrics and redistribution, controlling BGP path selection and scaling with route reflectors or confederations, deploying LDP and segment routing, running PIM-SM and SSM with MSDP or mLDP, and keeping forwarding alive during failures with BFD, NSR/NSF, and TI-LFA. Expect scenario-heavy items where you choose between plausible designs or diagnose a described fault. The Cisco SPRI 300-510 case studies are 5 cases and about 2,433 words.
1OSPF NSSA Redistribution and Translator Election
A service provider runs OSPFv2 in areas 0, 10, and 20. Area 10 is an NSSA with two ASBRs, R10-1 and R10-2, both redistributing the same summarized BGP prefix 198.51.100.0/24.

AS 65010 uses a BGP confederation with sub-AS 65001 (core) and 65002 (edge). Each sub-AS has one route reflector: RR1 in 65001, RR2 in 65002.

An ISP is migrating a six-router core to SR-MPLS. R1 through R4 support SR with a common SRGB of 16000-23999 and prefix-SID indices 10-60.
504 words, about 3 min4PIM-SM/MSDP Failure and SSM Migration
A content provider uses ASM group 239.100.1.1 for a market-data feed. Two data centers each have a PIM-SM RP: RP-A 10.1.1.1 and RP-B 10.2.2.2, configured as an Anycast RP pair with MSDP peering between the loopbacks.

A regional ISP runs SR-MPLS with TI-LFA in its core. Aggregation routers A1 and A2 are dual-homed to core P1 and P2; BFD is enabled on all core links with a 300 ms interval and multiplier 3.
