Hi Experts !
We want to have an aggregate only announced when the VRRP vip route is active
on the local BGP speaker
Show route proto local shows the route
1##.123.456.100/32 *[Local/0] 02:15:41
Local via ge-0/0/6.0
As the local router is the vrrp master
ge-0/0/6.0 up 26 master Active A 0.677 lcl
1##.123.456.1
vip
1##.123.456.100
the aggregate config is:
route 1##.123.456.0/24 {
policy MATCH-VIP-vrrp-226;
tag 24;
the policy is
policy-statement MATCH-VIP-vrrp-226 {
term 1 {
from {
protocol local;
route-filter 1##.123.456.100/32 exact;
}
then accept;
}
term 2 {
then reject;
}
}
But the result is negative
lab@mx-2> show route protocol aggregate hidden
inet.0: 32 destinations, 43 routes (30 active, 0 holddown, 1 hidden)
Restart Complete
+ = Active Route, - = Last Active, * = Both
1##.123.456.0/24 [Aggregate] 00:19:46, tag 24
Reject
When removing the policy I do not see the VIP route as contributing route:
1##.123.456.0/24 (1 entry, 1 announced)
TSI:
KRT in-kernel 1##.123.456.0/24 -> {}
Aggregated into 1##.123.456.0/22
Page 0 idx 1, (group TELIA type External) Type 1 val 0x9556434 (adv_entry)
Advertised metrics:

*Aggregate Preference: 130

Task: Aggregate
Announcement bits (4): 0-KRT 4-Aggregate 5-BGP_RT_Background
6-Resolve tree 2
AS path: I (LocalAgg)

AS path list:
AS path: I Refcount: 1
Contributing Routes (1):
1##.123.456.0/25 proto Direct
So is this a bug ?
or why it is not possible to use a VRRP VIP route as contributing route when it
is shown as protocol local route in the routing table
Or are local routes not contributing even though they are active?
The local route state is : State: <Active NoReadvrt Int>
Or is there another way to do this ?
The HW is a MX SW is 13.3, but the test was done on a vMX with 14.1
Thanks for help
Alexander
