IPv4 & IPv6 End-user Reachability & L3VPN over SRv6

Hi everyone in this post, I want to show you some SRv6 configurations from my lab. So for those of you who don't really know about SRv6, so SRv6 is a protocol that one day might replace the MPLS. So we can call it as a successor of MPLS.

Because with SRv6 you actually doesn't need to run MPLS LDP / MPLS RSVP anymore in your network, but you still can carry multiple services like the MPLS does. And you can run pure IPv6 network in your backbone, with no MPLS, and still manage to deliver any other services to your customer, like IPv4, IPv6, L3VPN, also L2VPN using the SRv6.

This is the topology of the lab. We have 6 Router that will run the SRv6, we have 4 Host (H1,H2,H5,H6) that connected using IPv4 & IPv6. And also we have L3VPN that also connected using IPv4 & IPv6. In our backbone we only have IPv6 only, we are not configuring any IPv4. Maybe the only thing that look like IPv4 is the router-id for each device, and also the interface that connected to the Host, because the Host run IPv4 & IPv6.

And for the address allocation, its gonna look like this, we have this loopback allocation, router-id, and also the SRv6 Locator.

Loopback Address
R1 2001:db8::1/128
R2 2001:db8::2/128
R3 2001:db8::3/128
R4 2001:db8::4/128
R5 2001:db8::5/128
R6 2001:db8::6/128

Router ID
R1 10.0.0.1
R2 10.0.0.2
R3 10.0.0.3
R4 10.0.0.4
R5 10.0.0.5
R6 10.0.0.6

SRv6 Locator
R1 fcbb:bb00:1::/48
R2 fcbb:bb00:2::/48
R3 fcbb:bb00:3::/48
R4 fcbb:bb00:4::/48
R5 fcbb:bb00:5::/48
R6 fcbb:bb00:6::/48

This SRv6 Locator works similarly to MPLS Label Range. In MPLS if you configure a MPLS Label Range, lets say from 10000 to 19999, then the router will assign a Label from that particular range.

The same thing happen in SRv6, but the different is, we don't have something called Label in SRv6, because we are not using MPLS encapsulation, in SRv6 we have something calles Segment ID (SID). So when you configure a Locator using range fcbb:bb00:1::/48, your SRv6 will allocate the SID (Segment ID) from that particular range. Oh yeah also, when talking about SID, you actually have 2 type of SID: Global SID, and Local SID.

Global SID is a globally significant SID, this SID information is known in every single router that run SRv6. The example of this SID is Node SID. Node SID will tell the SRv6 router, how to reach that particular router. Lets say we have R1 and R6, R6 will advertise the Node SID information to R1, to tell the R1 how to reach R6.

Local SID, this SID information is locally significant, meaning that only that particular router need to know the information about this SID, other router doesn't really need to know this information. The example of this SID is the Adjacency SID/Adj SID, this type of SID will tell router how to reach particular interface on that particular router. So lets say if R6 want to forward some traffic using spesific interface, maybe that interface is not the best path, and R6 still want to use that interface to forward the traffic, you can use this Adj SID, to force R6 to forward the traffic using that particular link.

If you want to learn more about SRv6, maybe I'll create a dedicated post that will explain about SRv6. For now lets just jump the the full configuration on each router. And for the host config, its just IPv4 & IPv6 address and a default route.
