Hello: I am his friend; in fact this frr does not have any neighbors;
I have some screenshots here, I hope they can be of some help to you

How are you starting zebra and what does your configuration look like. I am not seeing this locally so I need proper recreation steps.

Sorry, I only replied to you now

I started frr through systemctl restart frr.service

The configuration is as follows

My system is centos7.8

A special situation that may help you is to ping the local ipv6 address

Thank you very much for your reply

Can you show also /etc/frr/daemons file?

[lijinxianglogo]

Can you show also /etc/frr/daemons file?

This file tells the frr package which daemons to start.

Sample configurations for these daemons can be found in

/usr/share/doc/frr/examples/.

ATTENTION:

When activating a daemon for the first time, a config file, even if it is

empty, has to be present and be owned by the user and group "frr", else

the daemon will not be started by /etc/init.d/frr. The permissions should

be u=rw,g=r,o=.

When using "vtysh" such a config file is also needed. It should be owned by

group "frrvty" and set to ug=rw,o= though. Check /etc/pam.d/frr, too.

The watchfrr, zebra and staticd daemons are always started.

bgpd=no
ospfd=yes
ospf6d=yes
ripd=no
ripngd=no
isisd=no
pimd=no
ldpd=no
nhrpd=no
eigrpd=no
babeld=no
sharpd=no
pbrd=no
bfdd=no
fabricd=no
vrrpd=no
pathd=no

If this option is set the /etc/init.d/frr script automatically loads

the config via "vtysh -b" when the servers are started.

Check /etc/pam.d/frr if you intend to use "vtysh"!

vtysh_enable=yes
zebra_options=" -A 127.0.0.1 -s 90000000 -f /etc/frr/zebra.conf"
bgpd_options=" -A 127.0.0.1 -f /etc/frr/bgpd.conf"
ospfd_options=" -A 127.0.0.1 -f /etc/frr/ospfd.conf"
ospf6d_options=" -A ::1 -f /etc/frr/ospf6d.conf"
ripd_options=" -A 127.0.0.1"
ripngd_options=" -A ::1"
isisd_options=" -A 127.0.0.1"
pimd_options=" -A 127.0.0.1"
ldpd_options=" -A 127.0.0.1"
nhrpd_options=" -A 127.0.0.1"
eigrpd_options=" -A 127.0.0.1"
babeld_options=" -A 127.0.0.1"
sharpd_options=" -A 127.0.0.1"
pbrd_options=" -A 127.0.0.1"
staticd_options="-A 127.0.0.1"
bfdd_options=" -A 127.0.0.1"
fabricd_options="-A 127.0.0.1"
vrrpd_options=" -A 127.0.0.1"
pathd_options=" -A 127.0.0.1"

configuration profile

#frr_profile="traditional"
#frr_profile="datacenter"

This is the maximum number of FD's that will be available.

Upon startup this is read by the control files and ulimit

is called. Uncomment and use a reasonable value for your

setup if you are expecting a large number of peers in

say BGP.

#MAX_FDS=1024

The list of daemons to watch is automatically generated by the init script.

##watchfrr_options=""

To make watchfrr create/join the specified netns, use the following option:

##watchfrr_options="--netns"

This only has an effect in /etc/frr//daemons, and you need to

start FRR with "/usr/lib/frr/frrinit.sh start ".

for debugging purposes, you can specify a "wrap" command to start instead

of starting the daemon directly, e.g. to use valgrind on ospfd:

ospfd_wrap="/usr/bin/valgrind"

or you can use "all_wrap" for all daemons, e.g. to use perf record:

all_wrap="/usr/bin/perf record --call-graph -"

the normal daemon command is added to this at the end.
