BFD question

[kriskrs]

Hello,

On Cisco 7600, I've the following commmand:

bfd interval 750 min_rx 500 multiplier 4 - on interface.

Now the service should be migrated to NCS540 with XR, how can be this translated because I don't have option "interval".

Thank you!

if you use BFD for BGP there is command under the

router bgp for bfd multiplier and min-rx

[kriskrs]

I need to use under interface, anyway in both cases, interface or BGP, there is no option

interval

and my questions if it will be up without

interval

option. I mention that on the other side is a customer, I cannot control/change the other end.

Thanks

Hello @kriskrs,

In Cisco IOS XR, the

equivalent

command for BFD on an interface does not include the

interval

parameter. Instead, you can configure the minimum interval, minimum receive interval, and multiplier using different commands.

bfd template <template-name>
min-interval 750

min-rx-interval 500

multiplier 4

-- Apply template on interface:

interface <interface-type> <interface-number>
bfd mode <template-name>


As concerned bgp instance apply template on the neighbor:

 

router bgp <AS-number>
bfd all-interfaces
neighbor <peer-IP-address> remote-as <peer-AS-number>
neighbor <peer-IP-address> bfd fast-detect
neighbor <peer-IP-address> fall-over bfd
neighbor <peer-IP-address> bfd template <template-name>

Yes he sure can use

bfd

template under interface.

Hello,

Very good info, but seems that in my XR version (7.2.2) I don't have this option.

bfd ?
bundle Option for BFD over Bundle
dampening Configure BFD dampening intervals
echo Configure BFD echo parameters
interface Configure BFD on an interface
ipv6 Ipv6 BFD checksum
multihop Configure BFD multihop
multipath Configure BFD multiple path
trap Configure BFD trap parameters
<cr>

In case of using

bfd without interval

it will remain down?

Even under BGP there are no options like template, fall

Thank you
