Hi,

Simply originate it and it will work (if your neighbour's policy accept a
prefix that long).

Re: BGP
hi,

i am not an expert in BGP either in cisco, here is my conf, could you mark
whats wrong ?


router bgp 32513
 bgp log-neighbor-changes
 neighbor 222.103.2.33 remote-as 12450
 neighbor 222.103.2.33 ebgp-multihop 255
 neighbor 222.103.2.33 route-map lan-radius out
!
ip bgp-community new-format
ip community-list 10 permit 0:12670
!
access-list 60 permit 84.133.145.45
access-list 60 permit 222.103.2.18
route-map lan-radius permit 10
 match ip address 60

Best regards

Re: BGP
Hi,

What do you want to achieve?
What prefix do you want to send?

Quoted text here. Click to load it
so it means it is a ebgp session

istn't that neighbor directly connected?

In this config you use route-map to permit only two hosts (access-list 60).
Please write what do you want to advertise and if it is directly
connected or not?

Re: BGP
hi,

i would send 84.133.145.45 and 222.103.2.18 to neighbor 222.103.2.33
remote-as 12450
remote peer is direcly connected by fibre


i have tried : (dont work)
router bgp 32513
 bgp log-neighbor-changes
 neighbor 222.103.2.33 remote-as 12450
 neighbor 222.103.2.33 ebgp-multihop 255
 neighbor 222.103.2.33 route-map lan-radius out
!
ip bgp-community new-format
ip community-list 10 permit 0:12450
!
!
ip prefix-list r1 seq 5 permit 84.133.145.45/32
!
ip prefix-list radius seq 5 permit 222.103.2.18/32
route-map lan-radius permit 10
 match ip address prefix-list radius r1 mosaica

Re: BGP
OK
AFAIK you should have these hosts in routing table (exact match).
If you don't have - create static routes
ip route 84.133.145.45 255.255.255.255 something
ip route 222.103.2.18 255.255.255.255 something

then:

router bgp 32513
  bgp log-neighbor-changes
  neighbor 222.103.2.33 remote-as 12450
  neighbor 222.103.2.33 route-map lan-radius out
  network 84.133.145.45 mask 255.255.255.255
  network 222.103.2.18 mask 255.255.255.255
!
ip bgp-community new-format
ip community-list 10 permit 0:12670
!
access-list 60 permit 84.133.145.45
access-list 60 permit 222.103.2.18
route-map lan-radius permit 10
  match ip address 60

should work

if you don't have any ibgp sessions you can delete route-map and=20
'neighbor 222.103.2.33 route-map lan-radius out' statement

Re: BGP
yes it's work fine
i can not ping 84.133.145.45 because it's vpdn address so i have routed this
to null and bgp propagate correctly this address to my neighbor


thank's for all
