Hello!
I can observe this problem on armish hardware.
Desc.: eigrpd and ladvd have their specific Cisco's packets. Both can send it,
but cannot see such packets from other peer devices.
I've tried to reproduce on Thecus N2100 with name rps1.ILAN1.rLAN and EIGRP
address 66.8.0.69
1.How to reproduce:
please start eigrpd with any config on armish platform.
my config:
# cat /etc/eigrpd40.conf
# $OpenBSD: eigrpd.conf,v 1.2 2015/12/25 21:50:07 gsoares Exp $
# global configuration
router-id 66.8.0.69
rdomain 40
# fib-update yes
# fib-priority-internal 28
# fib-priority-external 52
# IPv4
address-family ipv4 {
autonomous-system 800 {
maximum-paths 4
variance 8
default-metric 100000 10 255 1 1500
# redistribute connected
interface vlan40 {
hello-interval 3
holdtime 10
delay 20
bandwidth 1000000
}
}
}

PS: 66.8.0.0/24 vlan40 is my internal Internet emulation subnetwork
(pseudoInternet).
Be so kind, could you add -s option to eigrpd like in ospfd in order to run
multiple instances of eigrpd.
thank you,
Ivan
