Data Center QoD: What is EVPN Host Routed Bridging?

0:00 [Music]

0:12 hi my name is eric stinson from

0:13 juniper's product marketing team and

0:16 today we are continuing with our series

0:18 of question of the days regarding uh

0:21 evpn and

0:23 host router bridging or hrb so with me

0:26 i'm joined by wen lin

0:28 one of juniper's distinguished engineers

0:31 hi wen

0:32 hi eric

0:34 uh thank you for joining me um and today

0:37 you know

0:38 last question of the day we talked a

0:39 little bit about you know where we are

0:41 with the evpn and the data center um but

0:44 and he kind of mentioned host router

0:46 bridging so today what we'd like to do

0:48 is dig a little further into that and

0:50 what exactly is post router bridging or

0:52 hrb evpn host router bridging is a cloud

0:57 native approach to build the evpn data

0:59 centers

1:01 it can provide a scale-out solutions

1:04 with consistency

1:05 operational simplicity and at the same

1:08 time

1:09 increase your revenue growth

1:11 so compared to a traditional evpn data

1:14 center

1:15 where the intelligence of

1:18 evpn to build overlay network resigned

1:21 on the leaf device

1:22 for east west data center traffic in the

1:25 cross fabric

1:27 now remove the intelligence of the evpn

1:30 to establish virtualized overlay network

1:33 from the leaf device down to the end

1:36 station which connects directly to the

1:38 cross fabric

1:40 and

1:41 all the protocol that is used to

1:44 discover

1:45 and establish evpn over a tunnel right

1:49 now running on the device and the device

1:52 which is a host can be host or server

1:54 bare metal itself

1:57 with hiv

1:59 the

2:00 east-west traffic now travels from the

2:03 host

2:04 directly over the overlay tunnel to

2:07 another host

2:09 and the spine leaf data center

2:12 cross fabric become a real only the ip

2:16 transport

2:17 they are not aware of the network they

2:20 become the pure ip transport

2:24 for the evpn running on the host

2:27 most routed bridging today we provide

2:31 evpn multi-tenancy

2:34 and evpn bdn aware and the vdm based

2:38 service well thank you wen that was uh

2:41 that sounds pretty cool so it sounds

2:43 like hrb is going to have a lot of

2:45 advantages and i look forward to

2:47 continuing with this series as we move

2:49 and hear what some of those advantages

2:51 are as well as you know how juniper is

2:53 implementing uh hrb so thank you very

2:55 much

2:56 thank you eric
