Description

Routes inside a vrf or virtual-router aren't having their validation-state updated when ROA's change in the validation database despite the notification-rib option being included.

Lab testing shows notification-rib working correctly on Junos 20.4R3-S4.8, but broken on 22.4R3-S3.3, 23.4R2-S2.1, and 24.4R1.9.

Example of the issue on a production MX204:

user@MX> show version

Hostname: MX

Model: mx204

Junos: 22.4R3-S3.3

 

user@MX> show configuration routing-options validation

notification-rib [ nzpeer.inet.0 nzpeer.inet6.0 internet-and-nren.inet.0 internet-and-nren.inet6.0 ];

group rpki2-hlz {

session 172.24.65.50 {

port 8282;

local-address 172.23.0.23;

}

}

group rpki2-wlg {

session 172.24.64.50 {

port 8282;

local-address 172.23.0.23;

}

}

user@MX> show validation database record 130.123.0.0/16

RV database: default

Prefix Origin-AS Session State Mismatch

130.123.0.0/16-16 9433 172.24.65.50 valid

130.123.0.0/16-16 9433 172.24.64.50 valid

 

user@MX> show route table internet-and-nren.inet 130.123.0.0/16 active-path

 

internet-and-nren.inet.0: 47481 destinations, 91546 routes (47481 active, 0 holddown, 0 hidden)

+ = Active Route, - = Last Active, * = Both

 

130.123.0.0/16 *[BGP/170] 6w6d 03:09:14, MED 0, localpref 200

AS path: 9433 ?, validation-state: unknown

> to 210.7.39.54 via irb.5307

 

You'll note the incorrect validation state "unknown" when it should be "valid".

 

 

Symptoms

route validation-state wont change with the modification of the validation-database, unless the BGP route is flapped.

Solution

Further testing found this issue is introduced by PR1788277 fix.

After the RV component receives an update in any of the ROAs from the cache server, it is not relaying that to the BGP-RV broker for an import reevaluation of the routes based on that update. Resulting to which the validation-state of the routes are not getting updated.

At the time of this writing, the problem is understood by Juniper engineering team, the fix is under review.
