Tcl / Esperar: não é possível definir corretamente o valor da variável

Question

Estou tentando obter detalhes do túnel IPSec do roteador. Depois disso busque linhas com endereços IP.

Então, eu tenho o seguinte código:

send "show tunnel ipsec remote 10.10.10.10\r"
expect "local"
send "\r"

set outcome $expect_out(buffer)

set records [split $outcome "\n"]

foreach rec $records {
if {[regexp {\*.*$} $rec tunnel_name]} {
regsub -all "\r" $tunnel_name "" tunnel_name
regsub -all " " $tunnel_name "" tunnel_name
set NodeBInfo "Tunnel:\t $tunnel_name"

set command "show tunnel ipsec name $tunnel_name detail | include \"Remote IP\""
send "$command\r"
expect "local"
set outcome1 $expect_out(buffer)
set records1 [split $outcome1 "\n"]     
foreach rec1 $records1 {
if {[regexp {Remote IP :.*$} $rec1 remote_ip]} {
regsub -all "\r" $remote_ip "" remote_ip
append NodeBInfo "\t$remote_ip"
}
}
unset outcome1
unset command

set command "show tunnel ipsec name $tunnel_name detail | include \"IRAC IP\""
send "$command\r"
expect "local"
set outcome2 $expect_out(buffer)
set records2 [split $outcome2 "\n"]     
foreach rec2 $records2 {
if {[regexp {IRAC IP:.*$} $rec2 remote_ip2]} {
regsub -all "\r" $remote_ip "" remote_ip2
append NodeBInfo "\t$remote_ip2"
}
}
unset outcome2
unset command

puts "NodeBInfo $NodeBInfo\r"
}
}

Eu esperava o seguinte valor da variável NodeBInfo:

NodeBInfo Tunnel:         *ran_tunnel-10.10.10.10-4049 Remote IP : 10.10.10.10  Local IP    : 20.20.20.20   IRAC IP: 40.40.40.40 / 255.255.255.0

Mas eu só tenho:

NodeBInfo Tunnel:         *ran_tunnel-10.10.10.10-4049

Saída completa do script:

[local]Router#show tunnel ipsec remote 10.10.10.10
