Maipu 3840 MTU Details

Hi, Today one of my client raised a query about MP 3840 MTU details about all 4 Gig interface. 
As MP 3840 is aggregation router, some time we need to modify the MTU of interface as per requirement. 
So I would like share same details here, Which can be helpful for all. 
MP 3840 Gig 0, you can configure max MTU of 1800 under Gig 0  interface for any peer device.
But Gig 1/2/3 , if speed is configured as 100 M or negotiating with 100M peer device. Then it will support max MTU 1500. If negotiating with 1000M or configured as 1000M , then it can support max 1800 MTU.


Hope this information will help in some critical scenario.

Maipu 1800 IPv6 Testing - BGP+

MP1800 -xx Series Routers support OSPFv3, IPv6 RIPng, IPv6 IS-IS, IPv6 BGP4+ and static IPv6 routing.

In this section we will use above topology for IPv6 BGP+ testing. 

Configuration Template -

Router-A:

hostname R-A

ip mef

interface loopback0

 ipv6 enable

 ipv6 address 1::1/128

 exit

interface fastethernet0

 ipv6 enable

 ipv6 address 192::1/64

 exit

                            

router bgp 100

 no auto-summary

 no synchronization

 bgp router-id 1.1.1.1

 neighbor 192::2 remote-as 200

 no neighbor 192::2 activate

 address-family ipv6

  network 1::1/128  

###network loopback 0 into BGP+ session, then peer BGP neighbor can learned this routing ###

  neighbor 192::2 activate

  exit-address-family

 exit

Router-B:

hostname R-B

interface fastethernet0

 ipv6 enable

 ipv6 address 192::2/64

 exit

interface fastethernet1

 ipv6 enable

 ipv6 address 193::1/64

 exit

                                 

router bgp 200

 no auto-summary

 no synchronization

 bgp router-id 2.2.2.2

 neighbor 192::1 remote-as 100

 no neighbor 192::1 activate

 address-family ipv6

  neighbor 192::1 activate

  exit-address-family

 exit

Testing Results Output:

On Router - A

On Router - B

Router-B Routing Table:

Router-B can reach to Router-A Loopback 1::1/128.

This above testing is basic testing of IPv6. For more detailed configurations. You can download it from Maipu website.

Hope this post will help you for IPv6 understanding.
