Thank you so much sir! God bless you!
Thanks!
Very well explained
Excellent explanation!!!!!!!
Hello Sir, I have a question.
if we use same RD 100:1 for both customers what will happen then
You can not configure same rd for two different VRFs on same router
Excellent!!
Thanks a lot
Super expalantion one more thing guys vrfs, MP-BGP, RD and RT works on control plane but in data plane we have 2 labels one is LDP(for P-Router) and second is VPN Label attached(for PE-Router).
In next videos I have explained control plane and forwarding plane also 😊
@@TheNetworkShooters sorry bro i didn't watched the next vedio
are RD and RT value provided by ISP? can cust A & B have same RD and RT somehow but VRF takes care of route separation till PE1. what happens in PE1 then?
In two different vrf you can not have same RD value, if the network is of ISP they will use RD and RT also this is not something to be purchased, you can also run mpls in your own network depending on your requirement.
how Provider P routers handle vpnv4 routes? is there any change in rd ?
P routers doesn’t need the routes, they will handle the next hop ip for vpnv4 traffic which is into global RIB and for that they have the label.
why is that IBGP formed with loopback & not with physical IP ? one is loopback are virtual & always up, another is incase of traffic steering, incase physical or primary comes up then can use the same. right ?
Loopbacks are also very use useful for redundant paths, in case your physical link down you can not reach it from anywhere but loopback can be reached if you have any alternate path
Got confused with this..In some places it says 'RD is locally significant' and in someother it says "RD value must be a globally unique value to avoid conflict with other prefixes"..So want to be sure whether it is locally significant or globally significant
It’s locally significant so per device it must be unique per vrf even the router process will not allow you to use same rd for two vrf, but you can use same rd on different device but for the ease of operation you must use different rd for each vrf so that we can identify it by looking at the rd value, also we can check the routes with bgp command which are learned from a particular rd value...
Superb explanation.. Thanks.
Please add BGP Label Unicast concept also.
Sure Nitin bhai, we will cover everything in this series, upcming videos are more interesting control plane and forwarding plane flow of a prefix from one location to another keep watching brother
