bgp evpn Route type-1

[sachin30720041]

Hi All,

I have the following topology. R1,R2,R3 and R4 are CSR devices.

R1(gig2)---(gig2)R2----R3(gig2)----(gig2)R4

R1#

interface GigabitEthernet2
ip address 100.10.10.10 255.255.255.0

R4#

interface GigabitEthernet2
ip address 100.10.10.20 255.255.255.0

R2#

interface GigabitEthernet2
no ip address
service instance 10 ethernet
encapsulation untagged

l2vpn evpn instance 10 point-to-point
rd 20000:16
vpws context cust
service target 20016 source 20014
member GigabitEthernet2 service-instance 10

router bgp 16
bgp log-neighbor-changes
neighbor 3.3.3.3 remote-as 16
neighbor 3.3.3.3 update-source Loopback0
!
address-family l2vpn evpn
neighbor 3.3.3.3 activate
neighbor 3.3.3.3 send-community both
exit-address-family

R3#

interface GigabitEthernet2
no ip address
service instance 10 ethernet
encapsulation untagged

router bgp 16
bgp log-neighbor-changes
neighbor 2.2.2.2 remote-as 16
neighbor 2.2.2.2 update-source Loopback0
!
address-family l2vpn evpn
neighbor 2.2.2.2 activate
neighbor 2.2.2.2 send-community both
exit-address-family

l2vpn evpn instance 10 point-to-point
rd 20000:16
vpws context cust
service target 20014 source 20016
member GigabitEthernet2 service-instance 10

BGP evpn session is up on R2 and R3.

R2#show bgp l2vpn evpn
Route Distinguisher: 20000:16
*> [1][20000:16][00000000000000000000][20014]/23
:: 32768 ?
*>i [1][20000:16][00000000000000000000][20016]/23
3.3.3.3 0 100 0 ?

But still R1 can not ping R4.

Hi @sachin30720041 ,

You configuration looks good. Can you please post the Gi1 configuration from R2 and R3? What IOS-XE version are you using? You should try upgrading to the latest 17 version.

Hi Harold,

I am using cisco CML. I will try upgrading the version.

Router>show version
Cisco IOS XE Software, Version 16.11.01b
Cisco IOS Software [Gibraltar], Virtual XE Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 16.11.1b, RELEASE SOFTWARE (fc2)

Thanks,

Sachin

Hi @sachin30720041 ,

You should be able to get it working with the version you are running with the following modifications:

R2:

interface GigabitEthernet2
no service instance 10 ethernet

!

l2vpn evpn instance 10 point-to-point
rd 20000:16
vpws context cust
service target 20016 source 20014
member GigabitEthernet2
!

R3:

interface GigabitEthernet2
no service instance 10 ethernet

!

l2vpn evpn instance 10 point-to-point
rd 20000:16
vpws context cust
service target 20014 source 20016
member GigabitEthernet2
!
