Hi Experts
I have the following network setup
RA (AS 10) ---------------------RC (ISP 1 AS 11)
|
|
|
|
RC(ISP 2 AS 12)
I need to load balance between these two ISPs
I did the following:
===================================
Hostname RA
!
router bgp 10
no synchronization
bgp log-neighbor-changes
neighbor 150.10.10.2 remote-as 12
neighbor 150.10.10.2 route-map prepend-as in
neighbor 160.20.20.2 remote-as 11
neighbor 160.20.20.2 route-map prepend-as in
maximum-paths 2
no auto-summary
!
address-family nsap
maximum-paths 2
no synchronization
exit-address-family
!
route-map prepend-as permit 10
set as-path prepend 10
!
===================================================
Hostname RB
!
router bgp 11
no synchronization
bgp log-neighbor-changes
neighbor 160.20.20.1 remote-as 10
neighbor 160.20.20.1 default-originate
auto-summary
!
=====================================================
Hostname RC
!
!
router bgp 12
no synchronization
bgp log-neighbor-changes
neighbor 150.10.10.1 remote-as 10
neighbor 150.10.10.1 default-originate
auto-summary
!
=======================
I get the following when I did SHOW IP BGP
RA#show ip bgp
BGP table version is 2, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
* 0.0.0.0 150.10.10.2 0 0 10 12 i
*> 160.20.20.2 0 0 10 11 i
RA#
But when I did (SHOW IP ROUTE) I got an unexpected result :
RA#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static
route
o - ODR, P - periodic downloaded static route
Gateway of last resort is 160.20.20.2 to network 0.0.0.0
1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Loopback0
160.20.0.0/24 is subnetted, 1 subnets
C 160.20.20.0 is directly connected, Serial1/0
150.10.0.0/24 is subnetted, 1 subnets
C 150.10.10.0 is directly connected, Serial1/1
B* 0.0.0.0/0 [20/0] via 160.20.20.2, 00:10:18
RA#
Can anybody help me about this problem.
Thanks in advance.
