address-family vpnv4 & default-information originate in IOS 12.4.11T3

xiangjian.lin · ‎10-26-2007

The company wants to upgrade the 7206VXR from NPE-300 to NPE-G2. The currently IOS is c7200-p-mz.122-15.T17.bin.

The only 12.2 IOS which support NPE-G2 is 12.2.31-SBXX. Then 12.4.xTx.

So I pick up 12.4.11T3 (ED) SP SERVICES and 12.2.31-SB3x (ED) SERVICE PROVIDER.

Before I upgrade the production gear, I did some testing to ensure the new IOS is compatible

with the currently MPLS configuration and I found some problem.

Here's some of the current configuration,

address-family vpnv4

neighbor 202.x.x.x activate

neighbor 202.x.x.x route-reflector-client

neighbor 202.x.x.x next-hop-self

neighbor 202.x.x.x send-community extended

neighbor 202.x.Y.Y activate

neighbor 202.x.Y.Y route-reflector-client

neighbor 202.x.Y.Y next-hop-self

neighbor 202.x.Y.Y send-community extended

default-information originate

no auto-summary

exit-address-family

address-family ipv4 vrf voipcore

redistribute static metric 10 route-map voipcore

redistribute ospf 7001

default-information originate

no auto-summary

no synchronization

exit-address-family

The problem is under address-family vpnv4,

default-information originate, no auto-summary are no longer valid command

Also under address-family ipv4 vrf,

no auto-summary is no longer valid command.

It occurs in both IOS I mentioned.

I do not know which IOS I can use or what alternative configuration I can modify.

I might need to log a case to TAC but their respond sometimes is very slow and inefficacy.

Thanks in advanced for your help.

We're running many NPE-G2 since the moment they became available. Tested many images and came to conclusion that 12.4XD train is the most usable out of all that available for this platform. If you're not running LNS/LAC, you can take 12.4(4)XD7. If you're running LNS/LAC, you will likely face crashes with XD7. Either go with XD5 or open TAC case and ask for bug fix for LNS. Even if 12.4XD train based on T train, XD is the only one that has all functionality working properly. TAC will try to push you for T or SB, if this works for you - fine, but for us were too many bugs to fix, so we settled for XD at the moment.

Both auto-summary and default-info originate are available in XD and we use it often.

For your image you can use workaround to originate default route - 'network 0.0.0.0 mask 0.0.0.0'.

Thanks for your reply, iLya.

I did tried 12.4XD but it looks like the Cisco change their code completely.

For 122-15.T17, under address-family vpnv4,

r1(config)#router bgp 65003

r1(config-router)#address-f vpnv4

r1(config-router-af)#?

Router Address Family configuration commands:

auto-summary Enable automatic network number summarization

bgp BGP specific commands

default Set a command to its defaults

default-information Control distribution of default information

distribute-list Filter networks in routing updates

exit-address-family Exit from Address Family configuration mode

help Description of the interactive help system

neighbor Specify a neighbor router

no Negate a command or set its defaults

table-map Map external entry attributes into routing table

But for 12.4X or 12.2.SB,

r1(config-router)#address-f vpnv4

r1(config-router-af)#?

Router Address Family configuration commands:

bgp BGP specific commands

default Set a command to its defaults

exit-address-family Exit from Address Family configuration mode

help Description of the interactive help system

maximum-paths Forward packets over multiple paths

neighbor Specify a neighbor router

no Negate a command or set its defaults

timers Adjust routing timers

Both auto-summary and default-info originate are no longer available.

I am more concerned with no auto-summary...

Cheers
