Question in BGP Peering

[Forbes Jenalyn Rose]

Hi,

I would like to know how to check if we support bgp MD5 password and how to do the config.

I tried to enter the password given to me but it always encrypt as password 7.

Also, how to do I check how many IPv4 and IPv6 prefixes we advisertised.

Thanks in advance.

Regards,

Jenna

1. The command you configure using "neighbor password < password >" is MD5 authentication only

it shows password 7 in show run becasue you have configured " service password-encryption "

You can check the md5 support using the command like below

#sh ip bgp neighbors 10.0.0.2 | inc md

Flags: passive open, nagle, gen tcbs, md5

2. To check thetotal  advertisd routes to a IPV4 neighbor

#show ip bgp neighbor advertised-routes | inc Total

3. To check the advertised routes to ipv6 neighbor

show bgp ipv6 unicast neighbor advertised-routes | inc Total

Hi Raju,

When I type those commands to have given to me, there is no output.

1. They are asking if we support BGP MD5 password and if we are, they gave us the MD5 password.

router bgp

neighbor password

But this command encrypts the password in password 7. So does it mean we do not support MD5??

2. They are asking how many IPv4 and IPv6 addresses we will advertise to them.

This setup is a new bgp peer, so no active connection yet.

Another thing, do I need to configure both address-familyIPv4 and address-family IPv6??

Thank you!
