问题描述
执行./run_mme，./run_hss和./run_spgw之后，它创建了一个虚拟网络接口gtp0，但是，当我测试ping请求ping 8.8.8.8 -I gtp0时，结果在100% packet loss中。
这是SGW中的PGW和/usr/local/etc/oai/spgw.conf配置：
S-GW :
{
NETWORK_INTERFACES :
{
# S-GW binded interface for S11 communication (GTPV2-C),if none selected the ITTI message interface is used
SGW_INTERFACE_NAME_FOR_S11 = "lo"; # STRING,interface name,YOUR NETWORK CONfig HERE
SGW_IPV4_ADDRESS_FOR_S11 = "127.0.11.2/8"; # STRING,CIDR,YOUR NETWORK CONfig HERE
# S-GW binded interface for S1-U communication (GTPV1-U) can be ethernet interface,virtual ethernet interface,we don't advise wireless interfaces
SGW_INTERFACE_NAME_FOR_S1U_S12_S4_UP = "ens38"; # STRING,YOUR NETWORK CONfig HERE,USE "lo" if S-GW run on eNB host
SGW_IPV4_ADDRESS_FOR_S1U_S12_S4_UP = "192.168.3.101/24"; # STRING,YOUR NETWORK CONfig HERE
SGW_IPV4_PORT_FOR_S1U_S12_S4_UP = 2152; # INTEGER,port number,PREFER NOT CHANGE UNLESS YOU KNow WHAT YOU ARE DOING
# S-GW binded interface for S5 or S8 communication,not implemented,so leave it to none
SGW_INTERFACE_NAME_FOR_S5_S8_UP = "none"; # STRING,DO NOT CHANGE (NOT IMPLEMENTED YET)
SGW_IPV4_ADDRESS_FOR_S5_S8_UP = "0.0.0.0/24"; # STRING,DO NOT CHANGE (NOT IMPLEMENTED YET)
};
P-GW =
{
NETWORK_INTERFACES :
{
# P-GW binded interface for S5 or S8 communication,so leave it to none
PGW_INTERFACE_NAME_FOR_S5_S8 = "none"; # STRING,DO NOT CHANGE (NOT IMPLEMENTED YET)
# P-GW binded interface for sgi (egress/ingress internet traffic)
PGW_INTERFACE_NAME_FOR_sgi = "ens33"; # STRING,YOUR NETWORK CONfig HERE
PGW_MASQUERADE_sgi = "yes"; # STRING,{"yes","no"}. YOUR NETWORK CONfig HERE,will do NAT for you if you put "yes".
UE_TCP_MSS_CLAMPING = "no"; # STRING,"no"}.
};
# Pool of UE assigned IP addresses
# Do not make IP pools overlap
# first IPv4 address X.Y.Z.1 is reserved for GTP network device on SPGW
# normally no more than 16 pools allowed,but since recent GTP kernel module use,only one pool allowed (Todo).
IP_ADDRESS_POOL :
{
IPV4_LIST = (
"172.16.0.0/12" # STRING,YOUR NETWORK CONfig HERE.
);
};
# DNS address communicated to UEs
DEFAULT_DNS_IPV4_ADDRESS = "8.8.8.8"; # YOUR NETWORK CONfig HERE
DEFAULT_DNS_SEC_IPV4_ADDRESS = "8.8.4.4"; # YOUR NETWORK CONfig HERE
# Non standard feature,normally should be set to "no",but you may need to set to yes for UE that do not explicitly request a PDN address through NAS signalling
FORCE_PUSH_PROTOCOL_CONfigURATION_OPTIONS = "no"; # STRING,"no"}.
UE_MTU = 1500 # INTEGER
};
两个网络接口ens33和ens38中，只有其中一个被允许连接到Internet，而ens33也被PGW使用。
此外，我认为MME和HSS之间没有问题
