Configuration in ISR 4331 for Gigabit Ethernet and NIM-8CE1T1-PRI

[mohdhafiz.mohdsharif]

Hello,

I need a help to configure the ISR 4331.

Previously in IOS software, I've two routers with both have a Fast Ethernet port and E1 port and the configuration as below:

ROUTER 1:

controller E1 0/0

   framing NO-CRC4

   channel-group 0 timeslots 1-31

bridge irb

interface BVI1

   ip address 192.168.128.40 255.254.0.0

interface FastEthernet0/0

   no ip address

duplex auto

speed auto

bridge-group 1

interface Serial0/0:0

   no ip address

   encapsulation ppp

   bridge-group 1

bridge 1 protocol ieee

bridge 1 route ip

ROUTER 2:

Same configuration as ROUTER 1 except for Interface BVI1:

interface BVI1

   ip address 192.168.128.41 255.254.0.0

With these configurations I'm able to ping from end to end PC, 

eg: One PC terminated at Router 1 with IP address 192.168.1.10 can ping to one PC terminated at Router 2 with IP address 192.168.1.6.

However since the router need to be upgrade then the router use now is ISR4331 but I'm unable to replicate the configuration above to the new router.

How to configure the new router so I would able to ping from PC to PC like before?

Many thanks for your help.

Hello all,

Problem I'm facing now is the configuration of Interface BVI and bridge-group syntax could not be use in ISR 4431 (Sorry for the typo earlier as ISR 4331). Is there any way instead that using bridge-group syntax?

Hi,

Have you tried with "bridge-domain" command?

Hi Deepak,

The CLI show this when I type bridge-domain 1 under interface serial 0/1/0:1

R2#config t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int serial 0/1/0:1
R2(config-if)#bridge-domain 1
R2(config-bdomain)#

Do you have any idea what to do after that?

Thanks,

Hafiz

Hi, 

Look the below configuration:

bridge-domain 100
bridge-domain 200
bridge-domain 900
!

interface GigabitEthernet0/0/0
 description Sample Sub-IFs w/Dot1q
 no ip address
 no ip redirects
 no ip proxy-arp
 negotiation auto
 service instance 100 ethernet
  description Vlan100
  encapsulation dot1q 100
  rewrite ingress tag pop 1 symmetric
  bridge-domain 100
 !
 service instance 200 ethernet
  description Vlan200
  encapsulation dot1q 200
  rewrite ingress tag pop 1 symmetric
  bridge-domain 200
 !
 service instance 900 ethernet
  description Vlan900
  encapsulation dot1q 900
  rewrite ingress tag pop 1 symmetric
  bridge-domain 900
 !
!

interface BDI100
 description Vlan100 - L3
 ip address XX.XX.XX.XX XX.XX.XX.XX
 no ip redirects
 no ip proxy-arp
 ip pim sparse-mode
 ip tcp adjust-mss 1360
!
interface BDI200
 description Vlan200 - L3
 ip address 172.28.XX.XX 255.255.XX.XX
 no ip redirects
 no ip proxy-arp
 ip pim sparse-mode
 ip tcp adjust-mss 1360
!
interface BDI900
 description Vlan900 - L3
 ip address XX.XX.XX.XX XX.XX.XX.XX
 no ip redirects
 no ip proxy-arp
 ip tcp adjust-mss 1360
!

I hope it will helpful for you.

Hi Deepak,

I've follow the coding you gave earlier and managed to write it for GigabitEthernet 0/0/1 in the router:

!
interface GigabitEthernet0/0/1
no ip address
no ip redirects
no ip proxy-arp
shutdown
negotiation auto
service instance 100 ethernet
encapsulation dot1q 100
rewrite ingress tag pop 1 symmetric
bridge-domain 100
!

Also I've managed to write the Interface BDI100 in the Router (Use only one bridge domain for testing):

!
interface BDI100
ip address x.x.x.x x.x.x.x (replaced actual IP Address with x)
no ip redirects
no ip proxy-arp
ip pim sparse-mode
ip tcp adjust-mss 1360
!

However when I repeat the same I did in GigabitEthernet 0/0/1 into the Serial 0/1/0:1 the syntax Service Instance 100 was invalid:

R2(config)#interface serial0/1/0:1
R2(config-if)#no ip address
R2(config-if)#no ip redirects
R2(config-if)#no ip proxy-arp
R2(config-if)#negotiation auto
^
% Invalid input detected at '^' marker.

R2(config-if)#service instance 100 ethernet
^
% Invalid input detected at '^' marker.

Looks like the syntax could not be used for Serial.

Is there other way instead of using bridge-domain? Or we still could use the bridge-domain but need a different syntax in Serial configuration?

Thanks,

Hafiz
