well done!

consider adding the two rr through eth666 to the topology drawing...

you can automate that with: show ipv4 isis 1 graph 2
then you can update the generated .dot file with
https://github.com/rare-freertr/freeRtr/blob/master/src/net/freertr/spf/spfCalc.java#L56
to make it prettier a bit... :)

i'll add a knob for the isis/ospf/lsrp/rift show graph pretty to include that
line automatically...

btw that svg part of the rare/freertr repo, but i'm happy to include yours
too, if you have it somewhere... :)

sed repo's every readme.md for "tmppath" --> "temp"... sorry, i had to go...
:) then ./update-jar.sh to have it...

br,
cs

Hi !

Please find a new layer. What s new here is that:
- This layer is built on top of ISIS/LDP layer
- It enables internal BGP into the MAN core network
- Route reflection is enabled on router leh200001(id=2) and uro200001 (id=4)
for iBGP redundancy
- Route reflector, as a pure control plane function is isolated from the data
path and implemented
with freeRtr _VERY_COOL_ feature called VDC (Virtual Device Context) on
router leh200001(id=2) and uro200001 (id=4)

The new layer has been added here:
https://github.com/rare-freertr/validated-design/tree/main/000-man/004a-run-bgp-rr

This layer enable iBGP with RR, MPLS forwarding enabled in order to transform
the MAN into a MPLS service provider core
that can act as small ISP with (limited) partial routing and DCI MAN routers.
MPLS labels are distributed through LDP

Obviously for both IPv4 and IPv6 AFI !

@David, you can use 004a-run-bgp-rr folder in order to start your BGP
flowspec control plane simulation with FoD or Nemo.

Stay tuned,

All the best
Frederic
