Unable to ping from BDI to router

bhaskar038

Hi,

 

I'm trying to ping csr-1 to router. When router tries to ping, its sending ARP request and CSR is not responding. When CSR tries to ping, CSR is not even sending the ARP request.

 

The following is the configuration in CSR. Please let me know if I'm missing something.

int g 0
vrf forwarding mgmt-intf
no ip add
negotiation auto
service instance 10 ethernet
encapsulation 10 untagged
bridge domain 10
 
int bdi 10
mac-add 0aaa.0bbb.0ccc
ip add 10.10.10.10 255.255.255.0

Hi Miranda,

Thanks for your help. I simply changed from gig 0 (mgmt) to gig 1 and its working,

Hi Miranda,

 

I tested the same scenario by introducing Vlans.

 

On switch:

 

int f1/0 

switch port mode access

switch port access vlan 10

 

int f1/1 

switch port mode trunk

switch port trunk encapsulation dot1q

switch port trunk allowed vlan all

 

On CSR:

int g 2
no ip add
negotiation auto
no shut
service instance 10 ethernet
encapsulation dot1q 10
bridge domain 10
 
int bdi 10
ip add 10.10.10.10 255.255.255.0
encapsulation dot1q 10
no shut
 
 
On router:
 
int f0/0
ip add 10.10.10.1 255.255.255.0
no shut

Unable to ping from router to CSR.

1) Unable to view the MAC address of the router in CSR arp table.

2) From wireshark, I can see that 10.10.10.1 is sending the ARP response but, CSR is not savin?

Only with this config I cant tell you what´s wrong.

Try to share the full config.

@bhaskar038

Can you share the device config? If possible you can also share the GNS3 config file so that I can simulate the same scenarion on my machine. If the forum page does not allow you to attached the file, rename it with .txt extension and try again.

 Waiting for this information.
