PPR MPLS Basic Test Topology
The FRR PPR implementation for IS-IS is available here: https://github.com/opensourcerouting/frr/tree/isisd-ppr-sr
In this topology we have an IS-IS network consisting of 12 routers. CE1 and CE2 are the consumer edges, connected to R11 and R14, respectively. Three hosts are connected to the CEs using only static routes.
Router R11 advertises 6 PPR TLVs:
- IPv6 prefixes 6000:1::1/128 and 6000:2::1/128: {R11 - R21 - R22 - R23 - R14} (IPv6 Node Addresses).
- MPLS labels 500 and 501: {R11 - R21 - R22 - R23 - R14} (SR Prefix-SIDs).
- MPLS labels 502 and 503: {R11 - R21 - R31 - R32 - R41 - R33 - R34 - R23 - R14} (SR Prefix-SIDs)
PBR rules are configured on R11 and R14 to route the traffic between Host 1 and Host 3 using the first PPR tunnel, whereas all other traffic between CE1 and CE2 uses the second PPR tunnel.
Additional information:
- Addresses in the 4000::/16 range refer to interface addresses, where the last hextet corresponds to the node ID.
- Addresses in the 5000::/16 range refer to loopback addresses, where the last hextet corresponds to the node ID.
- Addresses in the 6000::/16 range refer to PPR-ID addresses.

PPR TLV processing needs to be enabled on all IS-IS routers using the ppr on
command. The advertisements of all PPR TLVs is done by router R11.

Ping Host 3 from Host2 and use tcpdump or wireshark to verify that the ICMP packets are being tunneled using MPLS LSPs and following the {R11 - R21 - R22 - R23 - R14} path. Here's a wireshark capture between R11 and R21:
Using traceroute
it's also possible to see that the ICMP packets are being tunneled through the IS-IS network:
root@host2:~# traceroute -n fd00:20:1::1 -s fd00:10:2::1
