vMX

Hello,

  I'm trying to running PIM Auto-RP on LSY using vMX as shown in below diagram

Configuration on Protocol PIM level on OBALA/vR1 & EVODOULA/vR1 is the following

show configuration protocols pim
dense-groups {
239.7.7.7/32;
239.8.8.8/32;
}
rp {

local address 192.168.1.1 # for OBALA vR1  and  192.168.2.1 for EVODOULA vR1
auto-rp mapping;
}
interface all {
mode sparse-dense;
version 2;
}

Configuration on Protocol PIM level on OBALA/vR2 & EVODOULA/vR2 is  the following

dense-groups {
239.7.7.7/32;
239.8.8.8/32;
}
rp {
auto-rp discovery;
}
interface all {
mode sparse-dense;
version 2;
}

But  while checking rps 

root@OBALA:vR1> show pim rps
Instance: PIM.master

address-family INET
RP address Type Mode Holdtime Timeout Groups Group prefixes
192.168.1.1 static sparse 150 None 0 224.0.0.0/4

root@EVODOULA:vR1> show pim rps
Instance: PIM.master

address-family INET
RP address Type Mode Holdtime Timeout Groups Group prefixes
192.168.2.1 static sparse 150 None 0 224.0.0.0/4

address-family INET6

on both vR2 

show pim rps
Instance: PIM.master

address-family INET

address-family INET6

root@EVODOULA:vR2>

Thank to help me to point on what is wrong ... 😉

Hello vlsingh,

  As you suggested , I added dense-group 224.0.1.39/32 and 224.0.1.40/32  on all PIM routers of my PIM domain.

 Below an example:

root@EVODOULA:vR1> show configuration protocols pim
dense-groups {
224.0.1.39/32;
224.0.1.40/32;
}
rp {
auto-rp mapping;
}
interface all {
mode sparse-dense;
version 2;
}

root@EVODOULA:vR1> show pim rps
Instance: PIM.master

address-family INET

address-family INET6

root@EVODOULA:vR1>

As you can  see no change ... 

Hi Vlsingh,

I added loopback address of each RP devices on protocol pim rp local address as shown below 

New config

root@OBALA:vR1> show configuration protocols pim
dense-groups {
224.0.1.39/32;
224.0.1.40/32;
}
rp {
local {
address 192.168.1.1;
}
auto-rp mapping;
}
interface all {
mode sparse-dense;
}

root@EVODOULA:vR1> show configuration protocols pim
dense-groups {
224.0.1.39/32;
224.0.1.40/32;
}
rp {
local {
address 192.168.2.1;
}
auto-rp mapping;
}
interface all {
mode sparse-dense;
version 2;
}

Results

Everything is OK ! Thanks to have shared the link 

Hi Besscou,

Thanks for the update. I was about to update that I don't see any rp address configuration. Gald that you already caught it.

If you think one of my responses helped to solve your query, please accept that response as solution.

Kudos are appreciated too!

Thanks
Vishal
