Hi,
I'm trying to get a small network going as described on http://www.netcraftsmen.net/welcher/papers/multicast03.html
The BSR & RP router is configured as below:
/*XORP Configuration File, v1.0*/
interfaces {
interface eth0 {
description: "??"
vif eth0 {
disable: false
address 192.168.4.2 {
prefix-length: 24
disable: false
broadcast: 192.168.4.255
}
}
disable: false
discard: false
}
interface eth1 {
description: "??"
vif eth1 {
disable: false
address 192.168.6.2 {
prefix-length: 24
disable: false
broadcast: 192.168.6.255
}
}
disable: false
discard: false
}
interface lo {
description: "Loopback interface"
vif lo {
disable: false
address 1.1.1.1 {
prefix-length: 32
disable: false
}
}
disable: false
discard: false
}
targetname: "fea"
}
protocols {
static {
route4 0.0.0.0/0 {
next-hop: 192.168.4.1
metric: 1
}
targetname: "static_routes"
disable: false
}
igmp {
targetname: "IGMP"
disable: false
interface eth0 {
vif eth0 {
disable: false
}
}
interface eth1 {
vif eth1 {
disable: false
}
}
traceoptions {
flag {
all {
disable: true
}
}
}
}
pimsm4 {
targetname: "PIMSM_4"
disable: false
interface eth0 {
vif eth0 {
disable: false
dr-priority: 1
}
}
interface eth1 {
vif eth1 {
disable: false
dr-priority: 1
}
}
interface register_vif {
vif register_vif {
disable: false
dr-priority: 1
}
}
bootstrap {
disable: false
cand-rp {
group-prefix 224.0.0.0/4 {
is-scope-zone: false
rp-priority: 192
rp-holdtime: 150
cand-rp-by-vif-name: "lo"
}
}
cand-bsr {
scope-zone 224.0.0.0/4 {
is-scope-zone: false
bsr-priority: 1
hash-mask-len: 30
cand-bsr-by-vif-name: "lo"
}
}
}
traceoptions {
flag {
all {
disable: false
}
}
}
}
fib2mrib {
disable: false
}
}
plumbing {
mfea4 {
targetname: "MFEA_4"
disable: false
interface eth0 {
vif eth0 {
disable: false
}
}
interface eth1 {
vif eth1 {
disable: false
}
}
interface register_vif {
vif register_vif {
disable: false
}
}
traceoptions {
flag {
all {
disable: true
}
}
}
}
}
fea {
unicast-forwarding4 {
disable: false
}
targetname: "fea"
}
Shortly after startup I see on a neighbor router
Xorp> show pim rps
RP Type Pri Holdtime Timeout ActiveGroups GroupPrefix
1.1.1.1 bootstrap 192 150 132 0 224.0.0.0/4
Xorp> show pim bootstrap
Active zones:
BSR Pri LocalAddress Pri State Timeout SZTimeout
1.1.1.1 1 0.0.0.0 0 AcceptPreferred 26 1196
But after a while these entries fanish after the Timeout and SZTimeout
However I regulary see incoming bootstrap messages from Elected BSR, so the Timeouts should be reset shouldnt they?
[ 2005/12/16 08:45:43 TRACE xorp_pimsm4 PIM ] RX PIM_BOOTSTRAP from 192.168.4.2 to 224.0.0.13 on vif eth2
What am I missing?
Thanks,
TM
